LKSFE - Less Known SFE Features - Japan Opensolaris Usergroup uses spec files!
Did you know, that the Japan OpenSolaris Usergroup maintains a repository of spec files on their own?
It is called contrib-spec-files. You can read the how-to here: https://pt.osdn.jp/projects/jposug/wiki/howtouse
And the list of packages can be read by browsing the repository itself: https://osdn.jp/projects/jposug/scm/hg/contrib-spec-files/tree/tip/specs/
Even written in japaneese language, you can understand a few parts of it (which I find amazing, and you may try an online translator on the page).
The japaneese Solaris friends have a number of extra packages in their repository compared to our spec-files-extra repository, which is good. What I like most about it, they've merged in the support for OmniOS.
You can see, copying of OpenSource is always a good thing!
Nice greetings to our Solaris friends in Japan!
