## A poor man's offline Rust playground.

# A simple cargo extension to setup and start a simple Rust project.
#
# Usage:
#
# cargo play [<name>]
#
# where `<name>` is the name of the project. If no name is provided a temporary
# directory will be used instead.
#
# Requires:
# - neovim
# - entr (http://eradman.com/entrproject/)
# - cargo
#
# TODO:
# - add ability to pass `cargo init` arguments
# - make `entr` detect new files
PLAY=""
BASE="$GIT/play"
# Check whether the script was invoked as a cargo command (i.e., `cargo play`).
