Control: retitle -1 ITP: giza -- lightweight scientific plotting library Control: owner -1 !
Hi again, (Cc to upstream: just to keep you informed. No action needed.) first tests show that giza works quite well for this purpose. So I will package it and use it for dpuser. If someone has a few scripts that can be used for tests, I'd be glad to include them for build and CI tests. It looks that we will get a really usable package of the two programs! For giza: I will create a git repository on alioth: https://anonscm.debian.org/cgit/debian-astro/packages/giza.git Best regards Ole Am 20.05.2016 um 22:00 schrieb Ole Streicher: > Hi Sergio, > > Sergio Gelato <sergio.gel...@astro.su.se> writes: >> * Ole Streicher [2016-05-20 09:54:15 +0200]: >>> HOWEVER: there is a major licensing issue.
