.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
A module that implements DOS-like globbing with a few enhancements.
It is largely compatible with perlglob.exe (the M$ setargv.obj
version) in all but one respect\*(--it understands wildcards in
directory components.
.PP
For example, \f(CW\*(C`<..\e\el*b\e\efile/*glob.p?>\*(C'\fR will work as expected (in
that it will find something like '..\elib\eFile/DosGlob.pm' alright).
Note that all path components are case-insensitive, and that
backslashes and forward slashes are both accepted, and preserved.
You may have to double the backslashes if you are putting them in
literally, due to double-quotish parsing of the pattern by perl.
.PP
Spaces in the argument delimit distinct patterns, so
\&\f(CW\*(C`glob(\*(Aq*.exe *.dll\*(Aq)\*(C'\fR globs all filenames that end in \f(CW\*(C`.exe\*(C'\fR
or \f(CW\*(C`.dll\*(C'\fR.  If you want to put in literal spaces in the glob
pattern, you can escape them with either double quotes, or backslashes.
e.g. \f(CW\*(C`glob(\*(Aqc:/"Program Files"/*/*.dll\*(Aq)\*(C'\fR, or
\&\f(CW\*(C`glob(\*(Aqc:/Program\e Files/*/*.dll\*(Aq)\*(C'\fR.  The argument is tokenized using
\&\f(CW\*(C`Text::ParseWords::parse_line()\*(C'\fR, so see Text::ParseWords for details
of the quoting rules used.
.PP
Extending it to csh patterns is left as an exercise to the reader.

A few dir-vs-file optimizations result in glob importation being
10 times faster than using perlglob.exe, and using perlglob.bat is
only twice as slow as perlglob.exe (\s-1GSAR 28\-MAY\-97\s0)
