CURSEL is a freeware FMLI (Forms and Menu Language Interpreter) implementation for Linux and UNIX.

Pipes, shell escapes, backquoted expressions, and file redirection are supported, and when compiled with ncurses 5, CURSEL supports color.
cvsq (CVS queued) is a tool that enables developers with a dial-up connection to work comfortably with CVS. It accepts same arguments as CVS but instead of directly processing them, cvsq stores all requests in a queue and handles them later. This way, you can mark several files for commit and upload them when you're connected to the Net.
Cyrprint converts postscript files generated by netscape (original pages must be in koi8 encoding). It can be used as a pass-through filter. It adds cyrillic fonts to the beginning of the file and substitutes font names in the original PS document. The substitution and addition of fonts can be controlled with styles.
