# Instrument the program with code coverage.

# This target is included for projects using [JSCoverage](http://siliconforks.com/jscoverage/)
# for code coverage.
#
# Note that JSCoverage support for Node.js was implemented by TJ Holowaychuk in
# a [fork](https://github.com/visionmedia/node-jscoverage).  Projects targetting
# Node.js should use that implementation.
#
# NOTE: The `lib-cov` directory is removed prior to executing `jscoverage` due
#       to the fact that jscoverage refuses to overwrite existing directories.
