Install Rcs On Windows
Is the RevisionControlSystem used by TWiki.
RCS on Windows - rcsmerge always fails. And while it seems that the Purdue packages provide source code for diff3, they don't provide you with a Win32 binary. If you've already installed diff3.exe from some other source, update your path to include its install location, or (less ideally) move the diff3.exe binary to a folder already named in your path.
It can be found at:
- Generally: http://www.uvm.edu/~ashawley/rcs/
- Unix: http://www.fsf.org/software/rcs/rcs.html <-- Note new address
- See also pages under TWikiOnUnix for links to platform-specific freeware sites
- Windows (GNU port): http://www.gnu.org/software/emacs/windows/faq10.html#where-rcs
- Windows (CygWin port): http://cygwin.com/ - just run
setup.exeand select 'rcs' package

RCS is probably the most challenging part of a TWikiOnWindows setup.
If you use the GNU port, be sure to use RCS_LF_ONLY=1; if using Cygwin, use Cygwin binary mode filesystem mounts (see CookbookLineEndingProblems, or just use the now well-tested WindowsInstallCookbook)

*nix Setup Troubles
Setting up RCS on a *nix (Unix) system is no walk in the park for some either. [whine, whine, whine] That's been my roadblock to setting up Twiki. I ended up installing a less-usable wiki temporarily, until I can find someone to help me out with RCS.

Has anyone found or written better instructions for the newbie for compiling this source onto an ISP? I'll check back here, but dropping me an email would be great too.
- See TWikiOnUnix and in particular TWikiOnSolaris, which has pointers to how to build RCS etc. -- RichardDonkin

Install On Windows
You might like to try the RcsLite option for TWiki. Note that this requires a recent beta or alpha (i.e. get code from CVS). RcsLite avoids the need for RCS, instead equivalent functionality is implemented in Perl.
