Based on some example sites, I created, what I think is, a layout-compliant site source which uses Maven as build type:
The problem is that I'm new on using the Apache CMS, so I'm not totally sure if this is completely fine.
I tried to build the site using this command line:
$ /path/to/apache/cms/build/build_external.pl --source-base /path/to/marmotta/svn/site/trunk --target-base /path/to/marmotta/svn/site/trunk --type maven
but I don't know how to further proceed.
Thanks for the kind support of all the INFRA team.
