CURSEL project is a freeware FMLI implementation, a small language that allows you to quickly make a form- and menu- based character interface to shell scripts and other programs.
CURSEL filenames normally start with either "Menu", "Form" or "Text".
For example, the command,
./cursel Menu.example
would interpret the contents of the file "Menu.example" and display an example Menu.
CURSEL provides a language similar to the AT&T FMLI shell. Note that the language is similar to, but certainly not the same as, a /bin/sh shell; in particular, backquoted expressions are NOT evaluated by a shell such as BASH, but rather by the builtin CURSEL "shell" (which does not have all features of e.g. BASH).
There are also a few CURSEL extensions:
1. text frames can use the "alignment" descriptor, a CURSEL extension, which allows you to left or right align text in a Text frame (centering and justification is also supported).
2. backquoted expressions can use () grouping of parentheses, as in the UNIX shell
