-# Standard targets generated by automake
-# Source: http://www.gnu.org/software/automake/manual/automake.html#Standard-Targets
-#
-# make all -  Build programs, libraries, documentation, etc. (same as make).
-# make install - Install what needs to be installed, copying the files from the package’s tree to 
system-wide directories.
-# make install-strip -  Same as make install, then strip debugging symbols. Some users like to trade space 
for useful bug reports...
-# make uninstall - The opposite of make install: erase the installed files. (This needs to be run from the 
same build tree that was installed.)
-# make clean -  Erase from the build tree the files built by make all.
-# make distclean -   Additionally erase anything ./configure created.
-# make check -    Run the test suite, if any.
-# make installcheck -    Check the installed programs or libraries, if supported.
-# make dist -     Recreate package-version.tar.gz from all the source files.
