The preferred method to test and install CppAD uses cmake.
The deprecated autotools procedure can be used for this purpose,
but it will eventually be removed.
For any sub-directory dir,
files of the form dir/makefile.am and dir/makefile.in
are used to support the autotools test and install procedure.
In addition,
the following files, in this directory, are also for this purpose:
compile,
config.guess,
config.sub,
configure.ac,
depcomp,
install-sh,
missing.
CppAD is available from Coin-OR with both the EPL and GPL licenses; see the versions link above. There is a separate tarball on the Coin-OR download page for each version and each license.
The web documentaition (linked above) is for the most recent version of CppAD.
The tarballs mentioned above include documention for the corresponding version
in a doc subdirectory.
See the file authors in this directory.
