Hi all,

currently the GRASS AddOns extensions are installed on GNU/Linux to


and on Windows to


This layout doesn't allow to install extensions for more installed
versions of GRASS. In other words, addons for GRASS 6.4.2 and GRASS
6.5 are installed on the same place

$HOME/.grass6/addons or $AppData\GRASS<major_version>\addons

I would suggest to change `addons` to `addons<full_version>`,
concretely GRASS 6.4.2 addons would be installed to

$HOME/.grass6/addons642 or $AppData\GRASS<major_version>\addons642

and GRASS 6.5 to

$HOME/.grass6/addons65 or $AppData\GRASS<major_version>\addons65

What do you think?

Other thing is that g.extension (or it's wxGUI front-end) should
automatically ask user to update his/her extensions when you upgrade
GRASS (libgis revision must be same for GRASS and the addons).
