-   Using `-' as the first character of the list of option characters
-   selects this mode of operation.

-   (aside from the initial '-') are option characters.  If `getopt'
-   is called repeatedly, it returns successively each of the option characters
-   from each of the option elements.
-
-   If `getopt' finds another option character, it returns that character,
-   updating `optind' and `nextchar' so that the next call to `getopt' can
-   resume the scan with the following option character or ARGV-element.
-
-   If there are no more option characters, `getopt' returns `EOF'.
-   Then `optind' is the index in ARGV of the first ARGV-element
-   that is not an option.  (The ARGV-elements have been permuted
-   so that those that are not options now come last.)
-
-   OPTSTRING is a string containing the legitimate option characters.
-   If an option character is seen that is not listed in OPTSTRING,
-   return '?' after printing an error message.  If you set `opterr' to
-   zero, the error message is suppressed but we still return '?'.
-
-   If a char in OPTSTRING is followed by a colon, that means it wants an arg,
-   so the following text in the same ARGV-element, or the text of the following
-   ARGV-element, is returned in `optarg'.  Two colons mean an option that
-   wants an optional arg; if there is text in the current ARGV-element,
-   it is returned in `optarg', otherwise `optarg' is set to zero.
-
-   If OPTSTRING starts with `-' or `+', it requests different methods of
-   handling the non-option ARGV-elements.
-   See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
-
-   Long-named options begin with `--' instead of `-'.
-   Their names may be abbreviated as long as the abbreviation is unique
-   or is an exact match for some defined option.  If they have an
-   argument, it follows the option name in the same ARGV-element, separated
-   from the option name by a `=', or else the in next ARGV-element.
-   When `getopt' finds a long-named option, it returns 0 if that option's
-   `flag' field is nonzero, the value of the option's `val' field
-   if the `flag' field is zero.
-
-   The elements of ARGV aren't really const, because we permute them.
-   But we pretend they're const in the prototype to be compatible
-   with other systems.
-
-   LONGOPTS is a vector of `struct option' terminated by an
-   element containing a name which is zero.
-
-   LONGIND returns the index in LONGOPT of the long-named option found.
-   It is only valid when a long-named option has been found by the most

-.TH PATCH 1 LOCAL
-.SH NAME
-patch - apply a diff file to an original
-.SH SYNOPSIS
-.B patch
-[options] [origfile [patchfile]] [+ [options] [origfile]]...
-.sp
-but usually just
-.sp
-.B patch
-<patchfile
-.SH DESCRIPTION
-.I Patch
-will take a patch file containing any of the four forms of difference
-listing produced by the
-.I diff
-program and apply those differences to an original file, producing a patched
-version.
-By default, the patched version is put in place of the original, with
-the original file backed up to the same name with the
-extension \*(L".orig\*(R" (\*(L"~\*(R" on systems that do not
-support long file names), or as specified by the
-\fB\-b\fP (\fB\-\-suffix\fP),
-\fB\-B\fP (\fB\-\-prefix\fP),
-or
-\fB\-V\fP (\fB\-\-version\-control\fP)
-options.
-The extension used for making backup files may also be specified in the
-.B SIMPLE_BACKUP_SUFFIX
-environment variable, which is overridden by the above options.
-.PP
-If the backup file already exists,
-.B patch
-creates a new backup file name by changing the first lowercase letter
-in the last component of the file's name into uppercase.  If there are
-no more lowercase letters in the name, it removes the first character
-from the name.  It repeats this process until it comes up with a
-backup file that does not already exist.
-.PP
-You may also specify where you want the output to go with a
-\fB\-o\fP (\fB\-\-output\fP)
-option; if that file already exists, it is backed up first.
-.PP
-If
-.I patchfile
-is omitted, or is a hyphen, the patch will be read from standard input.
-.PP
-Upon startup, patch will attempt to determine the type of the diff listing,
-unless over-ruled by a
-\fB\-c\fP (\fB\-\-context\fP),
-\fB\-e\fP (\fB\-\-ed\fP),
-\fB\-n\fP (\fB\-\-normal\fP),
-or
-\fB\-u\fP (\fB\-\-unified\fP)
-option.
-Context diffs (old-style, new-style, and unified) and
-normal diffs are applied by the
-.I patch
-program itself, while
-.I ed
-diffs are simply fed to the
-.I ed
-editor via a pipe.
-.PP
-.I Patch
-will try to skip any leading garbage, apply the diff,
-and then skip any trailing garbage.
-Thus you could feed an article or message containing a
-diff listing to
-.IR patch ,
-and it should work.
-If the entire diff is indented by a consistent amount,
-this will be taken into account.
-.PP
-With context diffs, and to a lesser extent with normal diffs,
-.I patch
-can detect when the line numbers mentioned in the patch are incorrect,
-and will attempt to find the correct place to apply each hunk of the patch.
-As a first guess, it takes the line number mentioned for the hunk, plus or
-minus any offset used in applying the previous hunk.
-If that is not the correct place,
-.I patch
-will scan both forwards and backwards for a set of lines matching the context
-given in the hunk.
-First
-.I patch
-looks for a place where all lines of the context match.
-If no such place is found, and it's a context diff, and the maximum fuzz factor
-is set to 1 or more, then another scan takes place ignoring the first and last
-line of context.
-If that fails, and the maximum fuzz factor is set to 2 or more,
-the first two and last two lines of context are ignored,
-and another scan is made.
-(The default maximum fuzz factor is 2.)
-If
-.I patch
-cannot find a place to install that hunk of the patch, it will put the
-hunk out to a reject file, which normally is the name of the output file
-plus \*(L".rej\*(R" (\*(L"#\*(R" on systems that do not support
-long file names).
-(Note that the rejected hunk will come out in context diff form whether the
-input patch was a context diff or a normal diff.
-If the input was a normal diff, many of the contexts will simply be null.)
-The line numbers on the hunks in the reject file may be different than
-in the patch file: they reflect the approximate location patch thinks the
-failed hunks belong in the new file rather than the old one.
-.PP
-As each hunk is completed, you will be told whether the hunk succeeded or
-failed, and which line (in the new file)
-.I patch
-thought the hunk should go on.
-If this is different from the line number specified in the diff you will
-be told the offset.
-A single large offset MAY be an indication that a hunk was installed in the
-wrong place.
-You will also be told if a fuzz factor was used to make the match, in which
-case you should also be slightly suspicious.
-.PP
-If no original file is specified on the command line,
-.I patch
-will try to figure out from the leading garbage what the name of the file
-to edit is.
-In the header of a context diff, the file name is found from lines beginning
-with \*(L"***\*(R" or \*(L"---\*(R", with the shortest name of an existing
-file winning.
-Only context diffs have lines like that, but if there is an \*(L"Index:\*(R"
-line in the leading garbage,
-.I patch
-will try to use the file name from that line.
-The Index line, if present, takes precedence over the context diff header.
-If no file name can be intuited from the leading garbage, you will be asked
-for the name of the file to patch.
-.PP
-If the original file cannot be found or is read-only, but a suitable
-SCCS or RCS file is handy,
-.I patch
-will attempt to get or check out the file.
-.PP
-Additionally, if the leading garbage contains a \*(L"Prereq: \*(R" line,
-.I patch
-will take the first word from the prerequisites line (normally a version
-number) and check the input file to see if that word can be found.
-If not,
-.I patch
-will ask for confirmation before proceeding.
-.PP
-The upshot of all this is that you should be able to say, while in a news
-interface, the following:
-.Sp
-	| patch -d /usr/src/local/blurfl
-.Sp
-and patch a file in the blurfl directory directly from the article containing
-the patch.
-.PP
-If the patch file contains more than one patch,
-.I patch
-will try to apply each of them as if they came from separate patch files.
-This means, among other things, that it is assumed that the name of the file
-to patch must be determined for each diff listing,
-and that the garbage before each diff listing will
-be examined for interesting things such as file names and revision level, as
-mentioned previously.
-You can give options (and another original file name) for the second and
-subsequent patches by separating the corresponding argument lists
-by a \*(L'+\*(R'.
-(The argument list for a second or subsequent patch may not specify a new
-patch file, however.)
-.PP
-.I Patch
-recognizes the following options:
-.TP 5
-.B "\-b suff, \-\-suffix=suff"
-causes
-.B suff
-to be interpreted as the backup extension, to be
-used in place of \*(L".orig\*(R" or \*(L"~\*(R".
-.TP 5
-.B "\-B pref, \-\-prefix=pref"
-causes
-.B pref
-to be interpreted as a prefix to the backup file
-name. If this argument is specified, any argument from
-.B \-b
-will be ignored.
-.TP 5
-.B "\-c, \-\-context"
-forces
-.I patch
-to interpret the patch file as a context diff.
-.TP 5
-.B "\-C, \-\-check"
-see what would happen, but don't do it.
-.TP 5
-.B "\-d dir, \-\-directory=dir"
-causes
-.I patch
-to interpret
-.B dir
-as a directory, and cd to it before doing
-anything else.
-.TP 5
-.B "\-D sym, \-\-ifdef=sym"
-causes
-.I patch
-to use the "#ifdef...#endif" construct to mark changes.
-.B sym
-will be used as the differentiating symbol.
-.TP 5
-.B "\-e, \-\-ed"
-forces
-.I patch
-to interpret the patch file as an
-.I ed
-script.
-.TP 5
-.B "\-E, \-\-remove\-empty\-files"
-causes
-.I patch
-to remove output files that are empty after the patches have been applied.
-.TP 5
-.B "\-f, \-\-force"
-forces
-.I patch
-to assume that the user knows exactly what he or she is doing, and to not
-ask any questions.  It assumes the following: skip patches for which a
-file to patch can't be found; patch files even though they have the
-wrong version for the ``Prereq:'' line in the patch; and assume that
-patches are not reversed even if they look like they are.
-This option does not suppress commentary; use
-.B \-s
-for that.
-.TP 5
-.B "\-t, \-\-batch"
-similar to
-.BR \-f ,
-in that it suppresses questions, but makes some different assumptions:
-skip patches for which a file to patch can't be found (the same as \fB\-f\fP);
-skip patches for which the file has the wrong version for the ``Prereq:'' line
-in the patch; and assume that patches are reversed if they look like
-they are.
-.TP 5
-.B "\-F number, \-\-fuzz=number"
-sets the maximum fuzz factor.
-This option only applies to context diffs, and causes
-.I patch
-to ignore up to that many lines in looking for places to install a hunk.
-Note that a larger fuzz factor increases the odds of a faulty patch.
-The default fuzz factor is 2, and it may not be set to more than
-the number of lines of context in the context diff, ordinarily 3.
-.TP 5
-.B "\-l, \-\-ignore\-whitespace"
-causes the pattern matching to be done loosely, in case the tabs and
-spaces have been munged in your input file.
-Any sequence of whitespace in the pattern line will match any sequence
-in the input file.
-Normal characters must still match exactly.
-Each line of the context must still match a line in the input file.
-.TP 5
-.B "\-n, \-\-normal"
-forces
-.I patch
-to interpret the patch file as a normal diff.
-.TP 5
-.B "\-N, \-\-forward"
-causes
-.I patch
-to ignore patches that it thinks are reversed or already applied.
-See also
-.B \-R .
-.TP 5
-.B "\-o file, \-\-output=file"
-causes
-.B file
-to be interpreted as the output file name.
-.TP 5
-.B "\-p[number], \-\-strip[=number]"
-sets the pathname strip count,
-which controls how pathnames found in the patch file are treated, in case
-the you keep your files in a different directory than the person who sent
-out the patch.
-The strip count specifies how many slashes are to be stripped from
-the front of the pathname.
-(Any intervening directory names also go away.)
-For example, supposing the file name in the patch file was
-.sp
-	/u/howard/src/blurfl/blurfl.c
-.sp
-setting
-.B \-p
-or
-.B \-p0
-gives the entire pathname unmodified,
-.B \-p1
-gives
-.sp
-	u/howard/src/blurfl/blurfl.c
-.sp
-without the leading slash,
-.B \-p4
-gives
-.sp
-	blurfl/blurfl.c
-.sp
-and not specifying
-.B \-p
-at all just gives you "blurfl.c", unless all of the directories in the
-leading path (u/howard/src/blurfl) exist and that path is relative,
-in which case you get the entire pathname unmodified.
-Whatever you end up with is looked for either in the current directory,
-or the directory specified by the
-.B \-d
-option.
-.TP 5
-.B "\-r file, \-\-reject\-file=file"
-causes
-.B file
-to be interpreted as the reject file name.
-.TP 5
-.B "\-R, \-\-reverse"
-tells
-.I patch
-that this patch was created with the old and new files swapped.
-(Yes, I'm afraid that does happen occasionally, human nature being what it
-is.)
-.I Patch
-will attempt to swap each hunk around before applying it.
-Rejects will come out in the swapped format.
-The
-.B \-R
-option will not work with
-.I ed
-diff scripts because there is too little
-information to reconstruct the reverse operation.
-.Sp
-If the first hunk of a patch fails,
-.I patch
-will reverse the hunk to see if it can be applied that way.
-If it can, you will be asked if you want to have the
-.B \-R
-option set.
-If it can't, the patch will continue to be applied normally.
-(Note: this method cannot detect a reversed patch if it is a normal diff
-and if the first command is an append (i.e. it should have been a delete)
-since appends always succeed, due to the fact that a null context will match
-anywhere.
-Luckily, most patches add or change lines rather than delete them, so most
-reversed normal diffs will begin with a delete, which will fail, triggering
-the heuristic.)
-.TP 5
-.B "\-s, \-\-silent, \-\-quiet"
-makes
-.I patch
-do its work silently, unless an error occurs.
-.TP 5
-.B "\-S, \-\-skip"
-causes
-.I patch
-to ignore this patch from the patch file, but continue on looking
-for the next patch in the file.
-Thus
-.sp
-	patch -S + -S + <patchfile
-.sp
-will ignore the first and second of three patches.
-.TP 5
-.B "\-u, \-\-unified"
-forces
-.I patch
-to interpret the patch file as a unified context diff (a unidiff).
-.TP 5
-.B "\-v, \-\-version"
-causes
-.I patch
-to print out its revision header and patch level.
-.TP 5
-.B "\-V method, \-\-version\-\-control=method"
-causes
-.B method
-to be interpreted as a method for creating
-backup file names.  The type of backups made can also be given in the
-.B VERSION_CONTROL
-environment variable, which is overridden by this option.
-The
-.B -B
-option overrides this option, causing the prefix to always be used for
-making backup file names.
-The value of the
-.B VERSION_CONTROL
-environment variable and the argument to the
-.B -V
-option are like the GNU
-Emacs `version-control' variable; they also recognize synonyms that
-are more descriptive.  The valid values are (unique abbreviations are
-accepted):
-.RS
-.TP
-`t' or `numbered'
-Always make numbered backups.
-.TP
-`nil' or `existing'
-Make numbered backups of files that already
-have them, simple backups of the others.
-This is the default.
-.TP
-`never' or `simple'
-Always make simple backups.
-.RE
-.TP 5
-.B "\-x number, \-\-debug=number"
-sets internal debugging flags, and is of interest only to
-.I patch
-patchers.
-.SH AUTHOR
-Larry Wall <lwall@netlabs.com>
-.br
-with many other contributors.
-.SH ENVIRONMENT
-.TP
-.B TMPDIR
-Directory to put temporary files in; default is /tmp.
-.TP
-.B SIMPLE_BACKUP_SUFFIX
-Extension to use for backup file names instead of \*(L".orig\*(R" or

-.B VERSION_CONTROL
-Selects when numbered backup files are made.

-.SH NOTES FOR PATCH SENDERS
-There are several things you should bear in mind if you are going to
-be sending out patches.
-First, you can save people a lot of grief by keeping a patchlevel.h file
-which is patched to increment the patch level as the first diff in the
-patch file you send out.
-If you put a Prereq: line in with the patch, it won't let them apply
-patches out of order without some warning.
-Second, make sure you've specified the file names right, either in a
-context diff header, or with an Index: line.
-If you are patching something in a subdirectory, be sure to tell the patch
-user to specify a 
-.B \-p
-option as needed.
-Third, you can create a file by sending out a diff that compares a
-null file to the file you want to create.
-This will only work if the file you want to create doesn't exist already in
-the target directory.
-Fourth, take care not to send out reversed patches, since it makes people wonder
-whether they already applied the patch.
-Fifth, while you may be able to get away with putting 582 diff listings into
-one file, it is probably wiser to group related patches into separate files in
-case something goes haywire.
-.SH DIAGNOSTICS
-Too many to list here, but generally indicative that
-.I patch
-couldn't parse your patch file.
-.PP
-The message \*(L"Hmm...\*(R" indicates that there is unprocessed text in
-the patch file and that
-.I patch
-is attempting to intuit whether there is a patch in that text and, if so,
-what kind of patch it is.
-.PP
-.I Patch
-will exit with a non-zero status if any reject files were created.
-When applying a set of patches in a loop it behooves you to check this
-exit status so you don't apply a later patch to a partially patched file.
-.SH CAVEATS
-.I Patch
-cannot tell if the line numbers are off in an
-.I ed
-script, and can only detect
-bad line numbers in a normal diff when it finds a \*(L"change\*(R" or
-a \*(L"delete\*(R" command.
-A context diff using fuzz factor 3 may have the same problem.
-Until a suitable interactive interface is added, you should probably do
-a context diff in these cases to see if the changes made sense.
-Of course, compiling without errors is a pretty good indication that the patch
-worked, but not always.
-.PP
-.I Patch
-usually produces the correct results, even when it has to do a lot of
-guessing.
-However, the results are guaranteed to be correct only when the patch is
-applied to exactly the same version of the file that the patch was
-generated from.
-.SH BUGS
-Could be smarter about partial matches, excessively \&deviant offsets and
-swapped code, but that would take an extra pass.
-.PP
-If code has been duplicated (for instance with #ifdef OLDCODE ... #else ...
-#endif),
-.I patch
-is incapable of patching both versions, and, if it works at all, will likely
-patch the wrong one, and tell you that it succeeded to boot.
-.PP
-If you apply a patch you've already applied,
-.I patch
-will think it is a reversed patch, and offer to un-apply the patch.
-This could be construed as a feature.

- * $Log: pch.c,v $
- * Revision 1.10  1997/10/23 02:44:22  ache
- * Add (unsigned char) cast to ctype macros
- *
- * Revision 1.9  1997/02/13 21:10:43  jmg
- * Fix a problem with patch in that is will always default, even when the
- * controlling terminal is closed.  Now the function ask() will return 1 when th
- * input is known to come from a file or terminal, or it will return 0 when ther
- * was a read error.
- *
- * Modified the question "Skip patch?" so that on an error from ask it will skip
- * the patch instead of looping.
- *
- * Closes PR#777
- *
- * 2.2 candidate

- * Revision 1.7  1996/04/11 10:13:40  markm
- * Priorities were broken. If there was an Index: line and *** /--- lines
- * with valid names, the *** /---names were taken first.
- * this broke eg:
- * Index: foo/Makefile
- * ==========
- * RCS <blah>
- * Retrieving <blah>
- * diff <blah>
- * *** Makefile <blah>
- * --- Makefile <blah>
- *
- * By trying to patch the Makefile in the _curent_ directory, rather than
- * the one in the foo/ directory.
- *
- * Revision 1.6  1995/09/14 04:33:35  gibbs
- * Give "Index" specified filenames preference over other filenames specified
- * in the diff.  This makes it so that diffs containing files in different
- * subdirectories that have the same name not patch the same file.  For example
- * a diff with patches to Makefile, des/Makefile, usr.bin/Makefile would attempt
- * to patch Makefile three times.
- *
- * Revision 1.5  1995/05/30  05:02:35  rgrimes
- * Remove trailing whitespace.
- *
- * Revision 1.4  1994/02/25  21:46:07  phk
- * added the -C/-check again.
- *
- * Revision 1.3  1994/02/17  22:20:36  jkh
- * Put this back - I was somehow under the erroneous impression that patch was in
- * ports, until I saw the the commit messages, that is! :-)  All changed backed out.
- *
- * Revision 1.2  1994/02/17  22:16:05  jkh
- * From Poul-Henning Kamp -  Implement a -C option to verify the integrity of
- * a patch before actually applying it.
- *
- * Revision 1.1.1.1  1993/06/19  14:21:52  paul
- * b-maked patch-2.10
- *
- * Revision 2.0.2.0  90/05/01  22:17:51  davison
- * patch12u: unidiff support added
- *
- * Revision 2.0.1.7  88/06/03  15:13:28  lwall
- * patch10: Can now find patches in shar scripts.
- * patch10: Hunks that swapped and then swapped back could core dump.
- *
- * Revision 2.0.1.6  87/06/04  16:18:13  lwall
- * pch_swap didn't swap p_bfake and p_efake.
- *
- * Revision 2.0.1.5  87/01/30  22:47:42  lwall
- * Improved responses to mangled patches.
- *
- * Revision 2.0.1.4  87/01/05  16:59:53  lwall
- * New-style context diffs caused double call to free().
- *
- * Revision 2.0.1.3  86/11/14  10:08:33  lwall
- * Fixed problem where a long pattern wouldn't grow the hunk.
- * Also restored p_input_line when backtracking so error messages are right.
- *
- * Revision 2.0.1.2  86/11/03  17:49:52  lwall
- * New-style delete triggers spurious assertion error.
- *
- * Revision 2.0.1.1  86/10/29  15:52:08  lwall
- * Could falsely report new-style context diff.
- *
- * Revision 2.0  86/09/17  15:39:37  lwall
- * Baseline for netwide release.
