I have Git installed for Windows in a C:\usr\bin\git directory. Then I added C:\usr\bin\git\usr\bin to the path (yes, that path is correct, not a copy/paste error). That directory has all sorts of Unix useful commands without the need for Cygwin - including less.exe for pager.
Another site is GnuWin32 which has *roff utils. I installed groff in C:\usr\bin\groff and with a simple batch file called 'man.bat', I can get man pages from the source.1 files - which I've put in C:\usr\share\man.
Why the hell don't I just use Linux!?!?
