portsにsubversionとsubversion-freebsdの二つがある件について

/usr/ports/develにsubversionとsubversion-freebsdがあってちょっと驚いた。
どうもsubversion-freebsdにはFreeBSDのソースレポジトリにアクセスする際に便利なよう、ちょっとしたカスタマイズがされているものらしい。

$ cat ./subversion-freebsd/pkg-descr 
Subversion is a version control system designed to be as similar to cvs(1) 
as possible, while fixing many outstanding problems with cvs(1).

This version adds patches that at this time are specific to the needs of
the FreeBSD Project src repository.  If you do not need to access that
repository you will want to use devel/subversion.

FreeBSDのForumより、subversion-freebsdに入っているもの。

There's 4 things in there:
- supply the repository location in keyword substitution
- set "display original" to true for merges
- provide 3 extra format characters in substitution
- Provide a default template that has FreeBSD project format:
+ "PR:",
+ "Submitted by:",
+ "Reviewed by:",
+ "Approved by:",
+ "Obtained from:",
+ "MFC after:",
+ "Security:",
