Configuration Information

If you want samu to be used whenever ninja is ran, move the original Ninja copy out of the way and make a symlink as the root user:

mv /usr/bin/ninja{,.old} &&
ln -svf samu /usr/bin/ninja

samu won't run on all logical CPUs or threads by default, similar to make. The premise to make it do so is the same process: pass -j<x>, where <x> is the number of logical CPUs you want used, whenever samu (or ninja if you made the symlink) is ran. You can get around having to specify it everytime by setting SAMUFLAGS and including -j<x> to it, like so:

export SAMUFLAGS=-j$(nproc)

A trick you can do is make SAMUFLAGS contain $MAKEFLAGS if MAKEFLAGS only contains the -j option, like so:

export SAMUFLAGS=$MAKEFLAGS

Add it to a Bash profile script like ~/.bash_profile to avoid having to set it after logging in.
