"""
Making Doxygen dependencies
===========================
Usage: doxydeps.py [OPTIONS] [depname] [doxyfile] [dir]
<depname> - is the dependency name, ie. the dependency file will
look like:
<depname>: file1.h file2.c ...
Depname defaults to basename of <doxyfile>.
<doxyfile> - is the path to the doxygen configuration file.
The default value is ./Doxyfile
<dir> - where the dependency file will be put.
The default value is .deps
if dir is '--' the dependencies will be printed on stdout
doxydeps reads the doxygen configuration file and produces a dependency
file with identical name + '.P' suffix under dependency directory.
