cxx-dependencies

Various scripts to see the dependencies between Cxx source files.

Requirements:

1. python 2
2. ponyORM

$ python -m pip install pony

graph.py

Draw dependencies graphs.

$ python graph.py -i zstd-dev/lib/common/ -r zstd-dev -n "example1" -o examples -d 999

$ python graph.py -i zstd-dev/lib/compress/zstd_fast.c -r zstd-dev -n "example2" -o examples -d 999

$ python graph.py -i zstd-dev/lib/compress/zstd_fast.c -r zstd-dev -n "example3" -o examples -d 1
