Subject: doxygen: Add \ref to references.
X-Git-Tag: v0.6.1~52^2~4
X-Git-Url: http://git.tue.mpg.de/?a=commitdiff_plain;h=f90e920b43eb4035ded061bb889c8e4d819a2a97;p=paraslash.git

doxygen: Add \ref to references.

This way doxygen issues a warning if the file/function/structure no
longer exists and a stale reference remains.
