Updated source distributions are not released for the Tidy project. To build the source version you'll need to check it out using CVS.
cvs -d:pserver:firstname.lastname@example.org:/cvsroot/tidy login cvs -z3 -d:pserver:email@example.com:/cvsroot/tidy co -P tidy
(Just press enter when prompted for password)
If you're building it on Linux, simply execute:
cd build/gmake make
And the binary will be built and placed in bin/tidy
Come across this error? Cannot find libtidy. Grab the source code from CVS, then execute:
sh build/gnuauto/setup.sh ./configure --prefix=/usr make make install
