"Driver and GUI for LMS7002M-based software-defined radio (SDR) platforms. The Lime Suite application software provides drivers and SDR application support for the LMS7002M RFIC, and hardware like the LimeSDR, NovenaRF7, and others." (taken from the project README)
This software suite contains a driver for net-wireless/soapysdr to make some SDR hardware based on Lime Microsystems LMS7002M available through SoapySDR. The suite also contains LimeUtil and LimeSuiteGUI to configure, update and test the SDR devices.
net-wireless/soapysdr should provide a USE flag (e.g. lime) to include this package.
