description	Applicative Common Lisp / A Computational Logic
long_description	\
		ACL2 (Applicative Common Lisp / A Computational		\
		Logic) is the successor to nqthm, the Boyer-Moore	\
		theorem prover.						\
									\
		ACL2 can be used to automatically or semi-automatically	\
		prove theorems and has been used extensively in real	\
		applications (e.g., proving the correctness of certain	\
		calculations in the floating point unit of the AMD K5	\
		microprocessor.						\
									\
		ACL2 is a very large, multipurpose system.		\
		You can use it as a programming language,		\
		a specification language, a modeling language,		\
		a formal mathematical logic, or a semi-automatic	\
		theorem prover. Because the meta-language is the same	\
		as the language (a subset of Common Lisp), it is very	\
		flexible.

#user_notes	Users who want to use ACL2 for serious work should	\
#		install the certify variant (sudo port install +certify), \
#		which will certify (i.e., prove all of the theorems)	\
#		in the included examples. This can take several hours.

# ACL2 is distributed without a version number attached to the files.
# So we can't tell if we have the latest version of a file by looking
# at the name.  (This breaks also MacPorts checksum handling.)
# Here, the files are manually fetched and renamed with a version number.
#
# MacPorts should always checksum the distribution files, instead
# of assuming that if a file's name is unchanged, the previously computed
# checksum is valid.
