Quick, case-insensitive file-find with unquoted wildcards.  Options to find(1) can be appended if desired.

Usage:

find matching files/directories etc that match *some*pattern*, displaying the full path, one match per line
ffl *some*pattern* [ *some*pattern* .. ] [ -{find-options} ]
same as above, but displaying relative paths
