Greetings, |
| 2 |
I am a bit of a newbie. I installed Gentoo a couple of weeks ago. |
| 3 |
My kids complained that all their favorite games were missing and |
| 4 |
didn't seem too impressed when I tried to explain the advantages of |
| 5 |
portage. They are 7 and 3. So I set about installing all the |
| 6 |
interesting games I could find on freshmeat, tucows, linuxforkids, |
| 7 |
etc. At first I was doing this from tarballs. Then I told myself |
| 8 |
this is stupid and I started writing ebuilds, using /usr/portage/skel.build |
| 9 |
and existing ebuilds as a base. Then I told myself even that is stupid |
| 10 |
and I wrote a shell script to take the URL of the tarball, fetch it, |
| 11 |
unpack it, poke around a bit, and produce a first guess at an ebuild. |
| 12 |
For fairly simple packages it produces something decent most of the |
| 13 |
time. I think that with a little work it could be quite useful. |
| 14 |
My first priority is to make it handle packages with more than |
| 15 |
one source file. Other suggestions are welcome. For what it's |
| 16 |
worth here it is: (excuse the inelegance of the implementation; |
| 17 |
I am a mathematician, not a programmer.) |
