#

#
# To build and install the package in the user environment, use:

#
## BUILD ONLY
#
# To build the package and add it to the nix store, use:
#
# $ nix-build

# To launch a shell with all dependencies installed in the environment, use one of the following:
# $ nix-shell
#
# After entering nix-shell, build it:
#
# $ configurePhase
# $ buildPhase
#
## NIXPKGS
#
# For all of the above commands, nixpkgs to use can be set the following way:
#
# a) by default it uses nixpkgs pinned to a known working version
#
# b) use nixpkgs from the system:
# --arg pkgs 0
#
# c) use nixpkgs at a given path
# --arg pkgs /path/to/nixpkgs
#
## CCACHE
#
# To enable ccache, use the following:
#
# --argstr ccache_dir /var/cache/ccache
# or when using nix-shell:
# --argstr ccache_dir ~/.ccache
#
# and make sure the given directory is writable by the nixpkgs group when using nix-build or nix-env -i,
# or the current user when using nix-shell
#
