ついでにCvsGraphも入れてみた。
1.以下のサイトでWindows用のバイナリをダウンロード。
http://www.akhphd.au.dk/~bertho/cvsgraph/
2.viewcvs.confを修正。
#
# Use CvsGraph. See http://www.akhphd.au.dk/~bertho/cvsgraph/ for
# documentation and download.
#
# use_cvsgraph = 0
use_cvsgraph = 1#
# if the cvsgraph program is not on the path, set this value
#
cvsgraph_path = C:\Program Files\cvsgraph-1.5.1-2-bin\
# cvsgraph_path = /usr/local/bin/
3.Apacheを再起動。
