[Discuss-gnuradio] is the USRP-hw still available now?

[??????]

hi,everyone:

  as i am new to RF pcb layout , i want the USRP daughter board PCB file to reference,i found a floder at "/root/usrp-hw"(http://gnuradio.org/redmine/projects/gnuradio/repository/revisions/8c8eeca9e2ae26c30f186bef23411d345acbc3f6/show/usrp-hw)

but i found some of those pcb files are created by gEDA(like tvrf.pcb).but others like rfx900.pcb,i wonder they are created by which tool?

as i tried,they are not created by those tools: altium designer/protel/gEDA/powerPCB.

plz help me if you know how to open them,thank you.

nail.
