License #18
Description
Simtools is licensed for most files, but some of them (mainly Makefiles) are unlicensed.
It's a good idea to add a parent license. Something like:
- All our contributions are freely available for use, copying, distribution in their original and modified form, but without any warranty.
- All Makefiles and documentation files are licensed under the license describes in the source code of the program.
- Third party programs may be licensed in their own right, but section 2 applies to them.
