yes, the idea is to have something that do all this
extra job of the Makefile and aliases automagically,
especially for small scripts -- I find myself so often
doing this kind of stuff.

mostly because of the libraries. I'm very often
switching between bash, php, sql, c++, perl, python,
java ... what bothers me the most is that i'm always
having to search for functions/parameters to do
something in such or such language, even for simple
things like trimming spaces from the end of a string.

so I'm trying to converge most of my work to one
language+library set.
