This program inverts wildcards for use in shell commands. For example, if you
want a list of all files in the current directory that do *not* end in `.o`,
run:

    ls $(not '*.o')

Note two things: You'll need to wrap `not` in the `$(...)` syntax to get
command substitution; and, you should wrap your glob(s) in single quotes to
prevent them from being expanded by the shell. You can specify more than one
glob; not will ignore files matching any of the provided globs.

To build, just run:

    make

To install, with privileges run:

    make install
