# Script to create an MDB "root" from a given set of BFU archives.  The root
# is created relative to the current directory, and the archive directory is
# specified as a parameter to this script.  For each set of archives we
# extract the complete set of /usr/include files and adb macros, as well as
# the 32-bit and 64-bit debugger libraries upon which mdb itself depends.
# The resulting tree of files can then be used as an argument to ``mdb -R''
# and for subsequent recompilation of MDB modules.
