# This is Jonathan Wilkes' nw.js variant of Pd-L2Ork nick-named "Purr-Data".
# Basically, it is Pd-L2Ork with the Tk GUI replaced with a JavaScript GUI
# implemented using nw.js (http://nwjs.io/).

# This is a "stable" snapshot of purr-data, meaning that it will be updated
# less frequently, and ideally only after some testing. As an alternative,
# there's also the purr-data-git package which builds straight from the latest
# upstream source, also available from the AUR.

# This package can be installed alongside pd-l2ork, as well as vanilla pd or
# pd-extended. To avoid conflicts with any of these, the main contents of the
# package can be found under /opt/purr-data by default (you can change this
# with the prefix variable below). Thus cyclist, pdsend, pdreceive and
# purr-data's main pd-l2ork binary itself can be found under
# /opt/purr-data/bin. The include and library files are under the same
# prefix. Also, a symbolic link purr-data is created under /usr/bin so that
# the program can be invoked easily from the command line. Likewise, links to
# the include and lib directories are created under /usr/include/purr-data and
# /usr/lib/purr-data, so that 3rd party externals know where to find these.
