# Subdirectories in which to run `make all'.  Including "." before
# @DOCDIR@ is an attempt to force all preceding directories in the list
# to be processed before the current directory so that the
# scripts/DOCSTRINGS libinterp/DOCSTRINGS files are built before
# attempting to build AUTHORS and BUGS.  Including "." again at the end
# of the list ensures that we display the "Octave sucessfully built..."
# message at the very end of the output from Make.  Another fix for
# these problems would be to continue eliminating the recursive make
# invocations so that we have better control over the dependencies and
# the order that things are built.
