Javascript interpreter
----------------------

Plowshare modules often need to execute javascript in order to interact with
file hosting websites. Since depending on how you manage the modules they might
be downloaded from the Internet and updated semi-automatically, there are
security implications to executing javascript from these untrusted modules.

As a precaution javascript support is disabled by default in the Debian package
of plowshare. You can re-enable it by setting the environment variable:

  PLOWSHARE_DEBIAN_JS=yes

You will also need to have an executable for a javascript interpreter installed
such as from the packages libmozjs-24-bin or rhino. If necessary you can tell
plowshare where to find the executable by using the environment variable
PLOWSHARE_JS which defaults to the value 'js'.


Managing modules
----------------

Plowshare includes a tool, plowmod, which lets you manually update the modules.
There was previously a plowshare-modules package in the Debian archives, but
the upstream preferences is to rely on plowmod rather than a distro package.
