# This library is no longer being maintained, and is included for backward
# compatibility with Perl 4 programs which may require it.

# programming techniques.
# Suggested alternative: Cwd
# Usage: $cwd = &fastcwd;
# This is a faster version of getcwd. It's also more dangerous because
# you might chdir out of a directory that you can't chdir back into.
