# Makefile -- top-level Makefile for NVM Library
#
# Use "make" to build the library.
#
# Use "make test" to build unit tests.
#
# Use "make check" to run unit tests.
#
# Use "make clean" to delete all intermediate files (*.o, etc).
#
# Use "make clobber" to delete everything re-buildable (binaries, etc.).
#
# Use "make cstyle" to run cstyle on all C source files
#
# Use "make rpm" to build rpm packages
#
# Use "make dpkg" to build dpkg packages
#
# Use "make source DESTDIR=path_to_dir" to copy source files
# from HEAD to 'path_to_dir/nvml' directory.
#
# As root, use "make install" to install the library in the usual
# locations (/usr/lib, /usr/include, and /usr/share/man).
# You can provide custom directory prefix for installation using
# DESTDIR variable e.g.: "make install DESTDIR=/opt"
