below is a perl program which changes the file name to [a-zA-Z0-9_-.]
only characterset, optionally only [a-z0-9_-.].
beware of a bug: this doesn't check if you there is already another
file w/ the same name as the translated one. say if you have 2 files:
'pq' and 'p q'. the script will move 'p q' to 'pq', obliterating the
old 'pq'.
