# cmake is a nice, cross-platform autotools replacement. Just give
# it a try.
#
# CMakeLists.txt for the 99-bootles-of-beer song. ;o)
#
# Copy the file to a directory of your choice and call cmake <PathToCMakeLists.txt>.
# Remember that cmake creates some files on execution, so using a clean, temporary
# directory makes it more easy to remove them all.
#
# Have a lot of fun. ;)
