With much regret, I had to remove these two programs - their license

doesn't permit us to distribute them. I think I should take some law
classes...

-Warsaw, 1998.10.21
-
-This is a port of Minix editor. It's small, fast and relatively
-robust. It can perform basic editing commands, block operations,
-and search and replace.
-
-The keybindings are just plain insane. I added a help screen
-(available under F1), and remapped some of the wildest keys to
-function keys. If you have some time and a bit of hacking skills,
-you're welcome to sanitize it. :-)
-
-A bit of warning: one of the reasons for its small size is that it
-doesn't use any termcap calls - it uses hardwired codes for 'cons25'
-terminal type. If you try to use it with some other terminal, you
-have to change them, or recompile with -DUNIX -ltermcap.
-
-This is a copyrighted software - see the file LICENSE. It allows
-you to use it for research and educational purposes only.

- *

-/*
- * Author: Michiel Huisjes.
- * 
- * 1. General remarks.
- * 
- *   Mined is a screen editor designed for the MINIX operating system.
- *   It is meant to be used on files not larger than 50K and to be fast.
- *   When mined starts up, it reads the file into its memory to minimize
- *   disk access. The only time that disk access is needed is when certain
- *   save, write or copy commands are given.
- * 
- *   Mined has the style of Emacs or Jove, that means that there are no modes.
- *   Each character has its own entry in an 256 pointer to function array,
- *   which is called when that character is typed. Only ASCII characters are
- *   connected with a function that inserts that character at the current
- *   location in the file. Two execptions are <linefeed> and <tab> which are
- *   inserted as well. Note that the mapping between commands and functions
- *   called is implicit in the table. Changing the mapping just implies
- *   changing the pointers in this table.
- * 
- *   The display consists of SCREENMAX + 1 lines and XMAX + 1 characters. When
- *   a line is larger (or gets larger during editing) than XBREAK characters,
- *   the line is either shifted SHIFT_SIZE characters to the left (which means
- *   that the first SHIFT_SIZE characters are not printed) or the end of the
- *   line is marked with the SHIFT_MARK character and the rest of the line is
- *   not printed.  A line can never exceed MAX_CHARS characters. Mined will
- *   always try to keep the cursor on the same line and same (relative)
- *   x-coordinate if nothing changed. So if you scroll one line up, the cursor
- *   stays on the same line, or when you move one line down, the cursor will
- *   move to the same place on the line as it was on the previous.
- *   Every character on the line is available for editing including the
- *   linefeed at the the of the line. When the linefeed is deleted, the current
- *   line and the next line are joined. The last character of the file (which
- *   is always a linefeed) can never be deleted.
- *   The bottomline (as indicated by YMAX + 1) is used as a status line during
- *   editing. This line is usually blank or contains information mined needs
- *   during editing. This information (or rather questions) is displayed in
- *   reverse video.
- * 
- *   The terminal modes are changed completely. All signals like start/stop,
- *   interrupt etc. are unset. The only signal that remains is the quit signal.
- *   The quit signal (^\) is the general abort signal for mined. Typing a ^\
- *   during searching or when mined is asking for filenames, etc. will abort
- *   the function and mined will return to the main loop.  Sending a quit
- *   signal during the main loop will abort the session (after confirmation)
- *   and the file is not (!) saved.
- *   The session will also be aborted when an unrecoverable error occurs. E.g
- *   when there is no more memory available. If the file has been modified,
- *   mined will ask if the file has to be saved or not.
- *   If there is no more space left on the disk, mined will just give an error 
- *   message and continue.
- * 
- *   The number of system calls are minized. This is done to keep the editor
- *   as fast as possible. I/O is done in SCREEN_SIZE reads/writes. Accumulated
- *   output is also flushed at the end of each character typed.
- * 
- * 2. Regular expressions
- *   
- *   Mined has a build in regular expression matcher, which is used for
- *   searching and replace routines. A regular expression consists of a
- *   sequence of:
- * 
- *      1. A normal character matching that character.
- *      2. A . matching any character.
- *      3. A ^ matching the begin of a line.
- *      4. A $ (as last character of the pattern) mathing the end of a line.
- *      5. A \<character> matching <character>.
- *      6. A number of characters enclosed in [] pairs matching any of these
- *        characters. A list of characters can be indicated by a '-'. So
- *        [a-z] matches any letter of the alphabet. If the first character
- *        after the '[' is a '^' then the set is negated (matching none of
- *        the characters). 
- *        A ']', '^' or '-' can be escaped by putting a '\' in front of it.
- *        Of course this means that a \ must be represented by \\.
- *      7. If one of the expressions as described in 1-6 is followed by a
- *        '*' than that expressions matches a sequence of 0 or more of
- *        that expression.
- * 
- *   Parsing of regular expression is done in two phases. In the first phase
- *   the expression is compiled into a more comprehensible form. In the second
- *   phase the actual matching is done. For more details see 3.6.
- * 
- * 
- * 3. Implementation of mined.
- * 
- *   3.1 Data structures.
- * 
- *      The main data structures are as follows. The whole file is kept in a
- *      double linked list of lines. The LINE structure looks like this:
- * 
- *         typedef struct Line {
- *              struct Line *next;
- *              struct Line *prev;
- *              char *text;
- *              unsigned char shift_count;
- *         } LINE;
- * 
- *      Each line entry contains a pointer to the next line, a pointer to the
- *      previous line and a pointer to the text of that line. A special field
- *      shift_count contains the number of shifts (in units of SHIFT_SIZE)
- *      that is performed on that line. The total size of the structure is 7
- *      bytes so a file consisting of 1000 empty lines will waste a lot of
- *      memory. A LINE structure is allocated for each line in the file. After
- *      that the number of characters of the line is counted and sufficient
- *      space is allocated to store them (including a linefeed and a '\0').
- *      The resulting address is assigned to the text field in the structure.
- * 
- *      A special structure is allocated and its address is assigned to the
- *      variable header as well as the variable tail. The text field of this
- *      structure is set to NIL_PTR. The tail->prev of this structure points
- *      to the last LINE of the file and the header->next to the first LINE.
- *      Other LINE *variables are top_line and bot_line which point to the
- *      first line resp. the last line on the screen.
- *      Two other variables are important as well. First the LINE *cur_line,
- *      which points to the LINE currently in use and the char *cur_text,
- *      which points to the character at which the cursor stands.
- *      Whenever an ASCII character is typed, a new line is build with this
- *      character inserted. Then the old data space (pointed to by
- *      cur_line->text) is freed, data space for the new line is allocated and
- *      assigned to cur_line->text.
- * 
- *      Two global variables called x and y represent the x and y coordinates
- *      from the cursor. The global variable nlines contains the number of
- *      lines in the file. Last_y indicates the maximum y coordinate of the
- *      screen (which is usually SCREENMAX).
- * 
- *      A few strings must be initialized by hand before compiling mined.
- *      These string are enter_string, which is printed upon entering mined,
- *      rev_video (turn on reverse video), normal_video, rev_scroll (perform a
- *      reverse scroll) and pos_string. The last string should hold the
- *      absolute position string to be printed for cursor motion. The #define
- *      X_PLUS and Y_PLUS should contain the characters to be added to the
- *      coordinates x and y (both starting at 0) to finish cursor positioning.
- * 
- *   3.2 Starting up.
- *      
- *      Mined can be called with or without argument and the function
- *      load_file () is called with these arguments. load_file () checks
- *      if the file exists if it can be read and if it is writable and
- *      sets the writable flag accordingly. If the file can be read, 
- *      load_file () reads a line from the file and stores this line into
- *      a structure by calling install_line () and line_insert () which
- *      installs the line into the double linked list, until the end of the
- *      file is reached.
- *      Lines are read by the function get_line (), which buffers the
- *      reading in blocks of SCREEN_SIZE. Load_file () also initializes the
- *      LINE *variables described above.
- * 
- *   3.3 Moving around.
- * 
- *      Several commands are implemented for moving through the file.
- *      Moving up (UP), down (DN) left (LF) and right (RT) are done by the
- *      arrow keys. Moving one line below the screen scrolls the screen one
- *      line up. Moving one line above the screen scrolls the screen one line
- *      down. The functions forward_scroll () and reverse_scroll () take care
- *      of that.
- *      Several other move functions exist: move to begin of line (BL), end of
- *      line (EL) top of screen (HIGH), bottom of screen (LOW), top of file
- *      (HO), end of file (EF), scroll one page down (PD), scroll one page up
- *      (PU), scroll one line down (SD), scroll one line up (SU) and move to a
- *      certain line number (GOTO).
- *      Two functions called MN () and MP () each move one word further or 
- *      backwards. A word is a number of non-blanks seperated by a space, a
- *      tab or a linefeed.
- * 
- *   3.4 Modifying text.
- * 
- *      The modifying commands can be separated into two modes. The first
- *      being inserting text, and the other deleting text. Two functions are
- *      created for these purposes: insert () and delete (). Both are capable
- *      of deleting or inserting large amounts of text as well as one
- *      character. Insert () must be given the line and location at which
- *      the text must be inserted. Is doesn't make any difference whether this
- *      text contains linefeeds or not. Delete () must be given a pointer to
- *      the start line, a pointer from where deleting should start on that
- *      line and the same information about the end position. The last
- *      character of the file will never be deleted. Delete () will make the
- *      necessary changes to the screen after deleting, but insert () won't.
- *      The functions for modifying text are: insert one char (S), insert a
- *      file (file_insert (fd)), insert a linefeed and put cursor back to
- *      end of line (LIB), delete character under the cursor (DCC), delete
- *      before cursor (even linefeed) (DPC), delete next word (DNW), delete
- *      previous word (DPC) and delete to end of line (if the cursor is at
- *      a linefeed delete line) (DLN).
- * 
- *   3.5 Yanking.
- * 
- *      A few utilities are provided for yanking pieces of text. The function
- *      MA () marks the current position in the file. This is done by setting 
- *      LINE *mark_line and char *mark_text to the current position. Yanking
- *      of text can be done in two modes. The first mode just copies the text
- *      from the mark to the current position (or visa versa) into a buffer
- *      (YA) and the second also deletes the text (DT). Both functions call
- *      the function set_up () with the delete flag on or off. Set_up ()
- *      checks if the marked position is still a valid one (by using
- *      check_mark () and legal ()), and then calls the function yank () with
- *      a start and end position in the file. This function copies the text
- *      into a scratch_file as indicated by the variable yank_file. This
- *      scratch_file is made uniq by the function scratch_file (). At the end
- *      of copying yank will (if necessary) delete the text. A global flag
- *      called yank_status keeps track of the buffer (or file) status. It is
- *      initialized on NOT_VALID and set to EMPTY (by set_up ()) or VALID (by
- *      yank ()). Several things can be done with the buffer. It can be
- *      inserted somewhere else in the file (PT) or it can be copied into
- *      another file (WB), which will be prompted for.
- * 
- *   3.6 Search and replace routines.
- * 
- *      Searching for strings and replacing strings are done by regular
- *      expressions. For any expression the function compile () is called
- *      with as argument the expression to compile. Compile () returns a
- *      pointer to a structure which looks like this:
- * 
- *         typedef struct regex {
- *              union {
- *                    char *err_mess;
- *                    int *expression;
- *              } result;
- *              char status;
- *              char *start_ptr;
- *              char *end_ptr;
- *         } REGEX;
- *      
- *    If something went wrong during compiling (e.g. an illegal expression
- *    was given), the function reg_error () is called, which sets the status
- *    field to REG_ERROR and the err_mess field to the error message. If the
- *    match must be anchored at the beginning of the line (end of line), the
- *    status field is set to BEGIN_LINE (END_LINE). If none of these special
- *    cases are true, the field is set to 0 and the function finished () is
- *    called.  Finished () allocates space to hold the compiled expression
- *    and copies this expression into the expression field of the union
- *    (bcopy ()). Matching is done by the routines match() and line_check().
- *    Match () takes as argument the REGEX *program, a pointer to the
- *    startposition on the current line, and a flag indicating FORWARD or
- *    REVERSE search.  Match () checks out the whole file until a match is
- *    found. If match is found it returns a pointer to the line in which the
- *    match was found else it returns a NIL_LINE. Line_check () takes the
- *    same arguments, but return either MATCH or NO_MATCH.
- *    During checking, the start_ptr and end_ptr fields of the REGEX
- *    structure are assigned to the start and end of the match. 
- *    Both functions try to find a match by walking through the line
- *    character by character. For each possibility, the function
- *    check_string () is called with as arguments the REGEX *program and the
- *    string to search in. It starts walking through the expression until
- *    the end of the expression or the end of the string is reached.
- *    Whenever a * is encountered, this position of the string is marked,
- *    the maximum number of matches are performed and the function star ()
- *    is called in order to try to find the longest match possible. Star ()
- *    takes as arguments the REGEX program, the current position of the
- *    string, the marked position and the current position of the expression
- *    Star () walks from the current position of the string back to the
- *    marked position, and calls string_check () in order to find a match.
- *    It returns MATCH or NO_MATCH, just as string_check () does.
- *    Searching is now easy. Both search routines (forward (SF) and
- *    backwards search (SR)) call search () with an apropiate message and a
- *    flag indicating FORWARD or REVERSE search. Search () will get an
- *    expression from the user by calling get_expression(). Get_expression()
- *    returns a pointer to a REGEX structure or NIL_REG upon errors and
- *    prompts for the expression. If no expression if given, the previous is
- *    used instead. After that search will call match (), and if a match is
- *    found, we can move to that place in the file by the functions find_x()
- *    and find_y () which will find display the match on the screen.
- *    Replacing can be done in two ways. A global replace (GR) or a line
- *    replace (LR). Both functions call change () with a message an a flag
- *    indicating global or line replacement. Change () will prompt for the
- *    expression and for the replacement. Every & in the replacement pattern
- *    means substitute the match instead. An & can be escaped by a \. When
- *    a match is found, the function substitute () will perform the
- *    substitution.
- * 
- *  3.6 Miscellaneous commands.
- * 
- *    A few commands haven't be discussed yet. These are redraw the screen
- *    (RD) fork a shell (SH), print file status (FS), write file to disc
- *    (WT), insert a file at current position (IF), leave editor (XT) and
- *    visit another file (VI). The last two functions will check if the file
- *    has been modified. If it has, they will ask if you want to save the
- *    file by calling ask_save ().
- *    The function ESC () will repeat a command n times. It will prompt for
- *    the number. Aborting the loop can be done by sending the ^\ signal.
- * 
- *  3.7 Utility functions.
- * 
- *    Several functions exists for internal use. First allocation routines:
- *    alloc (bytes) and newline () will return a pointer to free data space
- *    if the given size. If there is no more memory available, the function
- *    panic () is called.
- *    Signal handling: The only signal that can be send to mined is the 
- *    SIGQUIT signal. This signal, functions as a general abort command.
- *    Mined will abort if the signal is given during the main loop. The 
- *    function abort_mined () takes care of that.
- *    Panic () is a function with as argument a error message. It will print
- *    the message and the error number set by the kernel (errno) and will
- *    ask if the file must be saved or not. It resets the terminal
- *    (raw_mode ()) and exits.
- *    String handling routines like copy_string(to, from), length_of(string)
- *    and build_string (buffer, format, arg1, arg2, ...). The latter takes
- *    a description of the string out out the format field and puts the
- *    result in the buffer. (It works like printf (3), but then into a
- *    string). The functions status_line (string1, string2), error (string1,
- *    string2), clear_status () and bottom_line () all print information on
- *    the status line.
- *    Get_string (message, buffer) reads a string and getchar () reads one
- *    character from the terminal.
- *    Num_out ((long) number) prints the number into a 11 digit field
- *    without leading zero's. It returns a pointer to the resulting string.
- *    File_status () prints all file information on the status line.
- *    Set_cursor (x, y) prints the string to put the cursor at coordinates
- *    x and y.
- *    Output is done by four functions: writeline(fd,string), clear_buffer()
- *    write_char (fd, c) and flush_buffer (fd). Three defines are provided
- *    to write on filedescriptor STD_OUT (terminal) which is used normally:
- *    string_print (string), putchar (c) and flush (). All these functions
- *    use the global I/O buffer screen and the global index for this array
- *    called out_count. In this way I/O can be buffered, so that reads or
- *    writes can be done in blocks of SCREEN_SIZE size.
- *    The following functions all handle internal line maintenance. The
- *    function proceed (start_line, count) returns the count'th line after
- *    start_line.  If count is negative, the count'th line before the
- *    start_line is returned. If header or tail is encountered then that
- *    will be returned. Display (x, y, start_line, count) displays count
- *    lines starting at coordinates [x, y] and beginning at start_line. If
- *    the header or tail is encountered, empty lines are displayed instead.
- *    The function reset (head_line, ny) reset top_line, last_y, bot_line,
- *    cur_line and y-coordinate. This is not a neat way to do the
- *    maintenance, but it sure saves a lot of code. It is usually used in
- *    combination with display ().
- *    Put_line(line, offset, clear_line), prints a line (skipping characters
- *    according to the line->shift_size field) until XBREAK - offset
- *    characters are printed or a '\n' is encountered. If clear_line is
- *	  TRUE, spaces are printed until XBREAK - offset characters.
- *	  Line_print (line) is a #define from put_line (line, 0, TRUE).
- *    Moving is done by the functions move_to (x, y), move_addres (address)
- *    and move (x, adress, y). This function is the most important one in
- *    mined. New_y must be between 0 and last_y, new_x can be about
- *    anything, address must be a pointer to an character on the current
- *    line (or y). Move_to () first adjust the y coordinate together with
- *    cur_line. If an address is given, it finds the corresponding
- *    x-coordinate. If an new x-coordinate was given, it will try to locate
- *    the corresponding character. After that it sets the shift_count field
- *    of cur_line to an apropiate number according to new_x. The only thing
- *    left to do now is to assign the new values to cur_line, cur_text, x
- *    and y.
- *

-This is a port of Minix /bin/sh shell.
-
-It's quite limited, but also quite small. One of most serious
-limitations is lack of support for user-defined functions. Also,

-.SH DESCRIPTION
-.PP
-.I Sh
-is the shell, which forms the user's main interface with the system.
-On startup, the shell reads /etc/profile and $HOME/.profile, if they exist,
-and executes any commands they contain.  The Minix shell has most of the
-features of the V7 (Bourne) shell, including redirection of input and output,
-pipes, magic characters, background processes, and shell scripts.  A brief
-summary follows, but whole books have been written on shell programming alone.
-.LP
-Some of the more common notations are:
-.PP
-.in +2.45i

-.LP
-The shell uses the following variables for specific purposes:
-.PP
-.in +2.25i
-.ta 2i
-.ti -2i
-SHELL	the path of the current shell
-.ti -2i
-HOME	the default value for the cd(1) command
-.ti -2i
-PATH	the directories to be searched to find commands
-.ti -2i
-IFS	the internal field separators for command strings
-.ti -2i
-PS1	the primary shell prompt
-.ti -2i
-PS2	the secondary shell prompt
-.in -2.25i
-.LP
-There are various forms of substitution on the shell command line:
-.PP
-.in +2.25i
-.ta 2i
-.ti -2i
-`...`	Command string between back-quotes is replaced by its output
-.ti -2i
-"..."	Permits variable substitution between quotes
-.ti -2i
-\&'...'	Inhibits variable substitution between quotes
-.ti -2i
-$VAR	Replaced by contents of variable VAR
-.ti -2i
-${VAR}	Delimits variable VAR from any following string
-.in -2.25i
-.LP
-The expressions below depend on whether or not VAR has ever been set.
-If VAR has been set, they give:
-.PP
-.in +2.25i
-.ta 2i
-.ti -2i
-${VAR-str}	Replace expression by VAR, else by str
-.ti -2i
-${VAR=str}	Replace expression by VAR, else by str and set VAR to str
-.ti -2i
-${VAR?str}	Replace expression by VAR, else print str and exit shell
-.ti -2i
-${VAR+str}	Replace expression by str, else by null string
-.in -2.25i
-.LP
-If a colon is placed after VAR, the expressions depend on whether or not
-VAR is currently set and non-null.
-.LP
-The shell has a number of built-in commands:
-.PP
-.in +2.25i
-.ta 2i
-.ti -2i
-:	return true status
-.ti -2i
-\&. fn	execute shell script fn on current path

-operators and flow control statements:
-.PP
-.in +3.50i
