# Usage: mis_dep <src file>
#
# Description: Given a source file, this program will find all library
#              dependencies that this source file's object will depend on.
#              The dependency tree is built using the library dependencies
#              from the TRICK HEADERs in the source files.  TRICK_CFLAGS
#              are used to actually find all files in the dependency tree.
