LaTeX MSC macro package is designed specialy to all people that prepare their texts with LaTeX and want to easily draw MSCs in texts.
Original package was developed by Victor Bos, Ton van Deursen, and Sjouke Mauw and it is implemented in PSTricks. This implementation is not suitable for converting created text to pdf with pdflatex.
To remove this drawback Tomas Fabry in his bachelor theses re-implemented the original package using TikZ & PGF. The new impletmentation is fully compatible with old version and support converting documents with pdflatex.
The current version is maintained by Adrian Farmadin, it supports new shapes and next version in development will remove problems with levels and coregion padding.
