phpdocr will download, prettify, and output PHP documentation for the function or class that is supplied on the command-line, much like perldoc does for Perl and ri does for Ruby. Unless you explicitly tell it not to, phpdocr will also cache the documentation locally for fast retrieval in the future.
Perl modules are notated in many different formats: "Foo/Bar/Baz.pm", "Foo::Bar", "Foo-Bar", etc. Module-Format allows one to take a list of modules in any format (including mixed ones) and output it in a consistent format that can be input to an installation program or an information querier.
Backshift is a deduplicating (variable-sized, content-based blocks), compressing (xz or bz2) backup program. Full saves and incrementals are pretty indistinct other than the amount of data transmitted, somewhat like with "rsync --link-dest" but without the huge number of hardlinks. It also de-duplicates large file content at a granularity of about 2 megabytes on average; there tends to be a unique copy of each file with size less than around 2 megabytes on average.
Japplis Toolbox is a compilation of text utilities in one application. It can encode and decode URL, Base64, Hex, SoundEx, or Metaphone. It can convert numbers from/to binary, octal, decimal, and hexadecimal, and to date. It gives you text information such as character count, word count, MD5, or SHA. You can get Java system properties, environment variables, or Swing default values. It checks and finds regular expressions. It can also manipulate lines of text by sorting, reversing, shuffling, deleting duplicates, trimming spaces, or numbering lines.
