Globbing
========
The archetypal use of wildcards is for matching against the files in
a directory, and making a list of all the matches. This is called
"globbing".
You could do this using `fnmatch', by reading the directory entries
one by one and testing each one with `fnmatch'. But that would be slow
(and complex, since you would have to handle subdirectories by hand).
The library provides a function `glob' to make this particular use
of wildcards convenient. `glob' and the other symbols in this section
are declared in `glob.h'.
