[ACTION REQUIRED v4] Retiring packages for F-18

[80]

Hi,

libgtksourceviewmm can be safely (?) dropped since it is no more
actively maintained and all packages i'm aware of that relied on it
moved to newer gtksourceviewmm{,3} packages (repoquery didn't find any
other packages relying on it)

repoquery --whatrequires "libgtksourceviewmm-1.0.so.2()(64bit)"
libgtksourceviewmm-devel-1:0.3.1-7.fc15.x86_64

best regards,
H.
