# To compile the Mongoose library and demo programs just do "make"
# in this directory.  The Mongoose/Makefile will then run cmake
# in the build directory.
#
# To install Mongoose in /usr/local/lib and /usr/local/include:
#
#   sudo make install
#
# To remove all compiled files and libraries (except installed ones):
#
#   make distclean
