No physical check on the filesystem, but a logical cleanup of a
path. On UNIX eliminated successive slashes and successive "/.".

Takes one argument, a file name, and returns the file name, if the
argument is likely to be a perl script. On MM_Unix this is true for
any ordinary, readable file.

destination and autosplits them. See L<ExtUtils::Install/DESCRIPTION>
