M - a software build tool

usage:

#Make the project using meson, cmake, or make/autotools
m

#Run the project modifiying environmental arguments
CXX=clang++ m

#Run the project tests
m t

#pass arguments to the test script when using CMake to only run "python" tests
m t -c "-R python"

#Cleanup the project
m c

#Install the project
m i

#See configured settings
m s

#Build and run tests in a different build root using clang
CXX=clang++ CC=clang m -b build_clang t

M supports a configuration file written in JSON in the root of the repository. Keys are the names of the options that show up in m s

For example, this file would set the command line options passed to the testing command to run only python test cases:

{
  "cmdline_test": ["-R", "python"]
}

The configuration file overridden defaults set by the plug-ins, and the configuration file is in turn overridden by command line arguments.
