modernish

Modernish is a library for shell script programming which provides features like safer variable and command expansion, new language constructs for loop iteration, and much more. Modernish programs are shell programs; the new constructs are mixed with shell syntax so that the programmer can take advantage of the best of both. There is no compiled code to install, as modernish is written entirely in the shell language. It can be deployed in embedded or multi-user systems in which new binary executables may not be introduced for security reasons, and is portable among numerous shell implementations. The installer can also bundle a reduced copy of the library with your scripts, so they can run portably with a known version of modernish without requiring prior installation.
