'''''notes about the install procedure for Gen2 RFID USRP Project (modified gnuradio library)'''''
notes about the install procedure for someone's modified gnuradio library:


This software/hardware allows the operator to read Gen2 RFIDs in the 900Mhz range.<BR>
This project has not yet been publicly distributed but the author tells us<BR>
it will be released soon. These notes are not an install recipe... rather they are<BR>
clarification to help describe the install procedure.<BR>
According to the README, this project was tested with gnuradio subversion changeset 10532...
