Python/SWIG scripting:
>>> homedir=python_grass6.G_home()
>>> print homedir
/home/hamish


"~" is expanded by the shell AFAIK, so that requires a shell to expand.
"$HOME" works for me, where doesn't it work Michael?*


On ms windows there is %HOMEPATH% and %USERPROFILE%.
No idea how they differ,

[*] GRASS must know where home is, as that's where it looks for .grassrc6.

lib/init/init.bat does:
  if "%HOME%"=="" set HOME=%USERPROFILE%
  set WINGISRC=%HOME%\.grassrc6

lib/init/init.sh does:
  GISRCRC="$HOME/.grassrc6"
