Packages for r5u87x – a bunch of userspace tools to help manage cameras based on Ricoh R5U87x chipsets (http://bitbucket.org/ahixon/r5u87x/)
Packaging request: bug #120434
The packages provided (both source and binary) include only the loader software and do not contain the microcode, whose copyright and license status is unclear. Instead, a simple shell script is provided that can download and install the microcode directly from the upstream repository.

The repo also contains a package called r5u87x-loader. This now serves only as a transitional package to r5u87x, and it is kept here only because it has been referenced in bug #120434.
