JSchemePlus
An hack of Jscheme with a lot of enhancements and additional features.
...It allows to redistribute a script in an executable JAR file of only ~40K and implements all of R4RS with a lot of additional functions, like: (execute command) (random) (sequence from up-to step) (split list element) (string-split string sub-string) (read-all-from-file file) (write-to-file file data) (file-size file) etc... For the complete list read the HELP file or type (help).
JSchemePlus needs only the Java Virtual Machine (version 6 or higher) that, in the case, is very easy to download and install.
