.IX Header "DESCRIPTION"
Text::Glob implements \fIglob\fR\|(3) style matching that can be used to match
against text, rather than fetching names from a filesystem.  If you
want to do full file globbing use the File::Glob module instead.

.IX Item "leading . must be explictly matched"
\&\f(CW\*(C`*.foo\*(C'\fR does not match \f(CW\*(C`.bar.foo\*(C'\fR.  For this you must either specify
the leading . in the glob pattern (\f(CW\*(C`.*.foo\*(C'\fR), or set
\&\f(CW$Text::Glob::strict_leading_dot\fR to a false value while compiling
the regex.
.ie n .IP """*"" and ""?"" do not match /" 4

.IX Item "* and ? do not match /"
\&\f(CW\*(C`*.foo\*(C'\fR does not match \f(CW\*(C`bar/baz.foo\*(C'\fR.  For this you must either
explicitly match the / in the glob (\f(CW\*(C`*/*.foo\*(C'\fR), or set
\&\f(CW$Text::Glob::strict_wildcard_slash\fR to a false value with compiling
the regex.
.SH "BUGS"
.IX Header "BUGS"
The code uses qr// to produce compiled regexes, therefore this module
requires perl version 5.005_03 or newer.
