You may have to double the backslashes if you are putting them in
literally, due to double-quotish parsing of the pattern by perl.
+Spaces in the argument delimit distinct patterns, so
+C<glob('*.exe *.dll')> globs all filenames that end in C<.exe>
+or C<.dll>. If you want to put in literal spaces in the glob
+pattern, you can escape them with either double quotes, or backslashes.
+e.g. C<glob('c:/"Program Files"/*/*.dll')>, or
+C<glob('c:/Program\ Files/*/*.dll')>. The argument is tokenized using
+C<Text::ParseWords::parse_line()>, so see L<Text::ParseWords> for details
+of the quoting rules used.
+
Extending it to csh patterns is left as an exercise to the reader.
