unfortunately not - but one could always make an exception for 64.

A parsable format would be really nice here, as most of the information
needed is here.

Some standard fields as
- MAJOR version (e.g. 7)
- MINOR version (e.g. 1)
- PATCH version (e.g. 0)
- version EXTENSION (e.g. alpha)
- REVISION
- PLATFORM (e.g. x86_64-unknown-linux-gnu)
- grass BASE directory (e.g.
/home/vasek/dev/grass/gcc_trunk/dist.x86_64-unknown-linux-gnu) (I
assume the bin/ is in the base directory?)
- the CONFIGURE options - possibly split into separate and multiple
entries

A format like the Debian Control Files Syntax [1], which is defined and
easily parsable from different languages, would be the easiest.

I don't know if something like this can be still incorporated into
7.0.0?

This would be really nice and useful.

Thanks,

Rainer
