sounds good to do an wrapper which will download iraf
(like do flashplugin-nonfree). So I think that I'll go this way.

mentors: do you see any reason do not go this way ?

This is exactly what I've heard from the other sysadmin guy after
showing him your email.

we have heard about this, but the astronomer still want to use iraf.

wow, I'll have some conversation with the astronomers to see if they're
interested on this sextractor

I've made a small turn of everyones here and ask them which part of iraf and
which softwares to they used and which softwares
