     1.9 +#
    1.10 +# Version : 0.0.1 (alpha1)
    1.11 +#
    1.12 +# Documentation : none (will be avaible with beta version)
    1.13 +# The documentation will include an explanation of all fonction, how to 
    1.14 +# use them and how to improve this library.
    1.15 +#
    1.16 +# Devnotes (suppress while beta is released) :
    1.17 +# Add a generic download script ? -> download from tazlito & tazwok
    1.18 +# Add a generic create/cleanup script for tmp files ?
    1.19 +# check_for (pkg on cmd line, pkg, receipt, etc.) -> tazwok,tazpkg,list
    1.20 +#
    1.21 +# Note : as the work is progress some part are dirty code or some other
    1.22 +# are note finish. I update this because we need the libdep
