'''expandlibs_deps.py takes a list of key/value pairs and prints, for each
key, a list of all dependencies corresponding to the corresponding value.
Libraries are thus expanded, and their descriptor is also made part of this
list.
The list of key/value is passed on the command line in the form
"var1 = value , var2 = value ..."
