Generate CMSIS Pack for Release

This GitHub development repository lacks pre-built libraries of various software components (RTOS, RTOS2). In order to generate a full pack one needs to have the build environment available to build these libraries. This causes some sort of inconvenience. Hence the pre-built libraries may be moved out into separate pack(s) in the future.

To build a complete CMSIS pack for installation the following additional tools are required:

• doxygen.exe Version: 1.8.6 (Documentation Generator)
• mscgen.exe Version: 0.20 (Message Sequence Chart Converter)
• 7z.exe (7-Zip) Version: 16.02 (File Archiver)

Using these tools, you can generate on a Windows PC:

• CMSIS Documentation using the batch file gen_doc.sh (located in ./CMSIS/Doxygen).
• CMSIS Software Pack using the batch file gen_pack.sh (located in ./CMSIS/Utilities). The bash script does not generate the documentation. The pre-built libraries for RTX4 and RTX5 are not included within this repository.

The file ./CMSIS/DoxyGen/How2Doc.txt describes the rules for creating API documentation.
