This commit creates a wrapper with the purpose of gracefully execute Arcan
applications (appls, in Arcan jargon).
In a typical FHS system, Arcan can be invoked by a commandline like `arcan
<appl>`, or more generally `arcan <arcan options> <appl> <appl options>`. In
order to emulate this behaviour, this wrapper was crafted.
It `symlinkJoin`s Arcan and the appls, and sets the relevant environment
variables accordingly.
Arcan is a powerful development framework for creating virtually anything from
user interfaces for specialized embedded applications all the way to full-blown
standalone desktop environments.
At its heart lies a robust and portable multimedia engine, with a well-tested
and well-documented Lua scripting interface. The development emphasizes
security, debuggability and performance -- guided by a principle of least
surprise in terms of API design.
