In msdos there is a utility (whose name escapes me at the moment) that allows
you to compress executables (.exe's I mean) into a format that allows them to
be run from their compressed state. As far as i know the compressor adds a
little bit of code to the start of the compressed file to handle the
decompression and running and it is neat and fast. Does such a beast exist for
unix?
Example:
program.exe ----> compprogram.exe (smaller than original)
compprogram.exe - takes slightly longer than its uncompressed rival to start up
but after that there is no noticeable difference with most
programs
Thanks in advance,
Iain
