tool_data_table - refactoring
This MR will allow to integrate 3 tool_data_table
- tool_data_table_conf_cvmfs_byhand.xml
- tool_data_table_conf_cvmfs_managed.xml
- tool_data_table_conf_local.xml
The two first come with the cvmfs repo. So far, only the managed was integrate in usegalaxy.fr.
If we need to add a new .loc local or not, we should do that with the tool_data_table_conf_local.xml.
