description         gr-osmosdr provides support for OsmoSDR hardware within GNU Radio

categories          science comms
homepage            http://sdr.osmocom.org/trac/wiki/GrOsmoSDR
license             GPL-3
platforms           darwin macosx

set description_common {Includes OSMO SDR support GNU Radio source and sink blocks in C++, Python, and GNU Radio Companion (grc).  This port also offers a wrapper functionality for the FunCube Dongle, Ettus UHD, and rtl-sdr radios.  By using gr-osmosdr source you can take advantage of a common software API in your applications independent of the underlying radio hardware.}

        This port is kept up with the gr-osmosdr GIT 'master' branch, which is typically updated weekly to monthly, providing compatibility with GNU Radio release 3.7 API: the gnuradio and gnuradio-devel ports.  ${description_common}
