BUGFIX! The uppercase, lowercase, and pren utility couldn't rename directories on Unix because of a security check glitch. This has been fixed. My apologies to users of 1.0.7 who ended up with a bunch of zero-length files instead of renamed directories.
[Quick update from 1.0.7. There was a stupid typo in the README file, and I really wanted it fixed. Thus the 1.0.7a release.] And now, the rest of the news...
New utilities for file renaming: lowercase, uppercase, and pren (perl rename).
Also, a bug in the replace utility was fixed.
BUGFIX! Memory allocation code in randomize for standard input was goofed up, often causing out-of-memory errors when stdin was used. This is now fixed.
littleutils-1.0.5 has been released. Bugs in randomize and pngstrip were fixed, and some scripts were consolidated. Updating is highly recommended.
