+Revision history for Perl extension File::Glob
+
+0.00 Tue Dec 17 10:51:33 1996
+ - original version; created by h2xs 1.16
+
+0.90 Tue Dec 17 13:58:32 MST 1996
+ - implemented first pass access to glob(3),
+ but it's clumsy and it looks like it leaks
+ memory.
+
+0.91 Thu Sep 4 08:43:55 CDT 1997
+ - included CORE/config.h portability macros
+ - s/glob/bsd_glob/ to avoid calling and including the
+ system's glob stuff
+ - added GLOB_DEBUG for (surprise!) glob debugging
+ - tainted all filenames returned from &Glob::BSD::glob
+
+0.92 Tue Sep 30 08:31:57 CDT 1997
+ - only use lstat if HAS_LSTAT is defined
+ - renamed the glob flags to GLOB_*
+ - added GLOB_CSH convenience macro for csh(1) globbing
+ These changes thanks to Hans Mulder <hansm@icgned.nl>
+ - fixed an incompatibility with csh(1) globbing where a
+ pattern like {A*,b,c} wouldn't expand properly
+ - various compatibility changes
+ - fixed and added tests
+
+0.93 Wed Jul 1 10:39:47 CDT 1998
+ - renamed module to File::BSDGlob
+ - enabled 'globally' import directive to override the core
+ glob
+ - added Sarathy's tests for File::DosGlob
+0.99 Tue Oct 12 06:42:02 PDT 1999
+ - renamed module to File::Glob for incorporation into the
+ Perl source distribution
+ - ansified prototypes
+ - s/struct stat/Stat_t/
+ - split on spaces to make <*.c *.h> work (for compatibility)
+0.991 Tue Oct 26 09:48:00 BST 1999
+ - Add case-insensitive matching (GLOB_NOCASE)
+ - Make glob_csh case insensitive by default on Win32, VMS,
+ OS/2, DOS, RISC OS, and Mac OS
+ - Add support for :case and :nocase tags
+ - Hack to make patterns like C:* work on DOSISH systems
+ - Add support for either \ or / as separators on DOSISH systems
+ - Limit effect of \ as a quoting operator on DOSISH systems to
+ when it precedes one of []{}-~\ (to minimise backslashitis).

+
+File::Glob - Perl extension for BSD glob routine
+
+=head1 SYNOPSIS
+
+ use File::Glob ':glob';
+ @list = glob('*.[ch]');
+ $homedir = glob('~gnat', GLOB_TILDE | GLOB_ERR);
+ if (GLOB_ERROR) {
+ # an error occurred reading $homedir
+ }
+
+ ## override the core glob (core glob() does this automatically
+ ## by default anyway, since v5.6.0)
+ use File::Glob ':globally';
+ my @sources = <*.{c,h,y}>
+
+ ## override the core glob, forcing case sensitivity
+ use File::Glob qw(:globally :case);
+ my @sources = <*.{c,h,y}>
+
+ ## override the core glob forcing case insensitivity
+ use File::Glob qw(:globally :nocase);
+ my @sources = <*.{c,h,y}>
+
+=head1 DESCRIPTION
+
+File::Glob implements the FreeBSD glob(3) routine, which is a superset
+of the POSIX glob() (described in IEEE Std 1003.2 "POSIX.2"). The
+glob() routine takes a mandatory C<pattern> argument, and an optional
+C<flags> argument, and returns a list of filenames matching the
+pattern, with interpretation of the pattern modified by the C<flags>
+variable. The POSIX defined flags are:
+
+=over 4
+
+=item C<GLOB_ERR>
+
+Force glob() to return an error when it encounters a directory it
+cannot open or read. Ordinarily glob() continues to find matches.
+
+=item C<GLOB_MARK>
+
+Each pathname that is a directory that matches the pattern has a slash
+appended.
+
+=item C<GLOB_NOCASE>
+
+By default, file names are assumed to be case sensitive; this flag
+makes glob() treat case differences as not significant.
+
+=item C<GLOB_NOCHECK>
+
+If the pattern does not match any pathname, then glob() returns a list
+consisting of only the pattern. If C<GLOB_QUOTE> is set, its effect
+is present in the pattern returned.
+
+=item C<GLOB_NOSORT>
+
+By default, the pathnames are sorted in ascending ASCII order; this
+flag prevents that sorting (speeding up glob()).
+
+=back
+
+The FreeBSD extensions to the POSIX standard are the following flags:
+
+=over 4
+
+=item C<GLOB_BRACE>
+
+Pre-process the string to expand C<{pat,pat,...}> strings like csh(1).
+The pattern '{}' is left unexpanded for historical reasons (and csh(1)
+does the same thing to ease typing of find(1) patterns).
+
+=item C<GLOB_NOMAGIC>
+
+Same as C<GLOB_NOCHECK> but it only returns the pattern if it does not
+contain any of the special characters "*", "?" or "[". C<NOMAGIC> is
+provided to simplify implementing the historic csh(1) globbing
+behaviour and should probably not be used anywhere else.
+
+=item C<GLOB_QUOTE>
+
+Use the backslash ('\') character for quoting: every occurrence of a
+backslash followed by a character in the pattern is replaced by that
+character, avoiding any special interpretation of the character.
+(But see below for exceptions on DOSISH systems).
+
+=item C<GLOB_TILDE>
+
+Expand patterns that start with '~' to user name home directories.
+
+=item C<GLOB_CSH>
+
+For convenience, C<GLOB_CSH> is a synonym for
+C<GLOB_BRACE | GLOB_NOMAGIC | GLOB_QUOTE | GLOB_TILDE>.
+
+=back
+
+The POSIX provided C<GLOB_APPEND>, C<GLOB_DOOFFS>, and the FreeBSD
+extensions C<GLOB_ALTDIRFUNC>, and C<GLOB_MAGCHAR> flags have not been
+implemented in the Perl version because they involve more complex
+interaction with the underlying C structures.
+
+=head1 DIAGNOSTICS
+
+glob() returns a list of matching paths, possibly zero length. If an
+error occurred, &File::Glob::GLOB_ERROR will be non-zero and C<$!> will be
+set. &File::Glob::GLOB_ERROR is guaranteed to be zero if no error occurred,
+or one of the following values otherwise:
+
+=over 4
+
+=item C<GLOB_NOSPACE>
+
+An attempt to allocate memory failed.
+
+=item C<GLOB_ABEND>
+
+The glob was stopped because an error was encountered.
+
+=back
+
+In the case where glob() has found some matching paths, but is
+interrupted by an error, glob() will return a list of filenames B<and>
+set &File::Glob::ERROR.
+
+Note that glob() deviates from POSIX and FreeBSD glob(3) behaviour by
+not considering C<ENOENT> and C<ENOTDIR> as errors - glob() will
+continue processing despite those errors, unless the C<GLOB_ERR> flag is
+set.
+
+Be aware that all filenames returned from File::Glob are tainted.
+
+=head1 NOTES
+
+=over 4
+
+=item *
+
+If you want to use multiple patterns, e.g. C<glob "a* b*">, you should
+probably throw them in a set as in C<glob "{a*,b*}>. This is because
+the argument to glob isn't subjected to parsing by the C shell. Remember
+that you can use a backslash to escape things.
+
+=item *
+
+On DOSISH systems, backslash is a valid directory separator character.
+In this case, use of backslash as a quoting character (via GLOB_QUOTE)
+interferes with the use of backslash as a directory separator. The
+best (simplest, most portable) solution is to use forward slashes for
+directory separators, and backslashes for quoting. However, this does
+not match "normal practice" on these systems. As a concession to user
+expectation, therefore, backslashes (under GLOB_QUOTE) only quote the
+glob metacharacters '[', ']', '{', '}', '-', '~', and backslash itself.
+All other backslashes are passed through unchanged.
+
+=item *
+
+Win32 users should use the real slash. If you really want to use
+backslashes, consider using Sarathy's File::DosGlob, which comes with
+the standard Perl distribution.

+Some issues left to take care of:
+
+ o sane ~ handling on non-Unix platforms
+
+ Currently on non-Unix, when the glob code encounters a tilde glob
+ (.e.g ~user/foo or ~/.cshrc), it simply returns that pattern
+ without doing any expansion (meaning perl will weed it out since a
+ file of that name isn't likely to exist).
+
+ Please, if you have strong feelings about how tilde expansion
+ should be done on your favorite non-Unix platform(s), submit a
+ patch.
+
+ o path separator handling
+
+ Guido's code contains the assumption that the path separator is one
+ character (byte, probably) in length. Win32 doesn't object to the
+ true slash as a separator. I imagine MacPerl could change the SEP
+ cpp #define to ":". I have no idea what it is for VMS. Again, if
+ you have ideas and especially patches, please feel free to share
+ them.
