# Otherwise make will think that lib.a will need to be remade when
# texmfmp.c is changed, even though it doesn't. The result is that we
# will see the ctangle calls for every cweb program, since ctangleboot
# depends on lib.a, but isn't getting remade. So this ad hoc variable is
# a copy of lib_a_SOURCES in lib/Makefile.am, with "${srcdir}/lib/" prepended.

# 
# This will run the triptrap-sh script
#   which then runs make TEST=triptest.test check-am,
#   which then runs the (srcdir file) triptest.test script;
#   its output will be in (builddir file) trip.diffs,
#   and triptest.out if the test failed,   
#   plus various created files in the tripdir/ subdirectory.
# The triptest.diffs file will have the actual abs_srcdir value replaced
#  with the constant string "SRCDIR" to minimize differences, and "../"
#  replaced with "./" to match the canonical output. Confusing. For the
#  real output, see triptest.log.
# 
# To build only tex, make -C $ww tex (i.e., in builddir) should do it.

# are built before any tests are run. If this is a problem, just have to
# edit the generated Makefile in builddir to remove the dependency.
