libero.exe (in Windows world) refuses to load a TCL script when it is called in the way ../libero.exe SCRIPT: project.tcl; The problem is the whitespace there, so ../libero.exe SCRIPT:project.tcl works fine.

Fix #100

They are now handled separately, as they aren't source files.

No need to add modules while fetching, as modules are always added during
creation.

Not clear how useful it is.  Break recursive fetch as it changes manifest_dict.
