Hi,
As long as I see there is no official public git (or other VCS) repository representing GLPK source code development branch. Is there any possibility that at least a read-only mirror will appear? This would provide somewhat widespread way of source code/history browsing, line blaming, vendoring (i.e. using git submodules), etc.
Moreover, if using github/gitlab as a hosting, it would open a convenient (IMHO, in comparison to mailing lists) way of bug tracking & contributing.
How do you feel about this idea?
