Hehe, semi-sensible is right!
For the package manager you should have the full name for the package (Fluid Corpus etc…), but that’s too long for a folder folder. In which case, it depends on what you want long term. Will the final version of the software exist as multiple packages (i.e. one for ‘Decomposition’ and one for ‘Manipulation’)? Or will it be a single package. If the latter, then I would go with maybe just “FluCoMa” as the folder name.
Actually looking at packages, a bunch of them have long names with spaces (“MC Movement Studies”, “Digital Orchestra Toolbox”, etc…), so maybe just having “Fluid Corpus Manipulation” as the folder name too would be the way to go.
