[GRASS-dev] GEM updates in CVS

[Benjamin Ducke]

Hi,

I just committed a number of changes to GEM in the CVS.
Changes:

- removed all interaction on the console to be consistent with GRASS
command line tools behaviour. This means that users may now have to su
before running GEM in order to install into a system-wide GRASS directory
- removed/changed everything that was not POSIX compliant. GEM now
compiles fine under MINGW32/MSYS, although I did not yet get a chance to
test if it's working
- the binary is now called gem6 instead of gem to avoid conflicts with
the Ruby tool
- added a few options
- updated documentation

This also required a minor tweak of the real-install action in the main
GRASS Makefile so that it now picks up the 'gem6' binary from the 'gem' dir.

Hope this comes in time for the 6.3 preview release. Can't wait to see
that happen!

Best,

Benjamin
