# Recursive rules, usually automatically generated by Automake.
# Since we do not use (yet) Automake, we mimic the behaviour as
# close as possible.
# Recursive wall of sub-directories is based on the variable
# SUBDIRS.  That variable usually contains the of sub-directories
# to be made in depth-first postfix.  However, that order can
# be changed to depth-first prefix by explicitly including "."
# in SUBDIRS.  Rules ending with '-ax' are those specific to the
# the current directory.  Notice that the '-ax' rules are similar 
# to Automake generated '-am'.
