XJudges' comments:
X
X   To use:
X    make am
X    am ant.test.mk
X
X    Like much of Posix, obfuscation has its place.  Your task is to
X    figure out where.
X
X    This entry comes complete with a Posix-like command description.
X    Interested Posix balloters should lobby the IEEE for an obfuscated
X    P1003 sub-committee.
X
X    We also suggest that you try:
X    make am
X    am Makefile am_clobber        <-- clobber everything except am
X    am Makefile all
X
X
XSelected notes from the author:
X
X    See the file ant.README.
