Chnorm is a simple command line utility for setting the owner, group, and the mode of given files and directories on a per file/per directory basis, recursively. It is especially useful if you often copy files with brain-dead permissions from filesystems not supporting the Unix permission scheme. It detects executables based on their contents and sets their permissions accordingly.
Launch is a menu for favorite applications and documents. Installing Launch creates a folder in the home directory called "Aliases". Any number of documents and shortcuts can be placed in there and arranged in a hierarchy of subfolders. At login, Launch scans this directory, and creates a menu in the status area from which these files can be opened instantly. There are no other options or features in the menu; just exactly what is found in "Aliases" at login and no more.
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.
