# Contrary to what its name could lead to think, this Shell script is not a
# GNU Autotools-based configure script. Instead, it triggers the CMake build
# system. That Shell script is intended to be used by standard CI (Continuous
# Integration) build-servers, such as Hudson/Jenkins for instance.
# The standard CI build-server often calls simple build preparation scripts,
# namely autogen.sh and/or configure in our case. Hence, the CI build-server
# will not fail when running this configure script. Better, the CMake framework
# will be invoked, thus improving the performance of the build.
#
# Even better, this configure script has itself been generated by an ad-hoc
# autogen.sh script. That latter can be seen from the Git repository only:
# it is not shipped with the project tar-ball.
#
# Parsing of options
# Note:
# -----
# The Hudson/Jenkins-based CI build-server often builds any simulator-related
# projects with the same set up of options:
# ./configure --with-stdair=/opt/stdair

# to be built. Like that, the CI build-server has not to be bothered by
# any specific set up.
