The router began as a port of FreeRouting and has grown its own engine
(negotiated congestion, tree nets, exact checks, axis escapes), and
'freeroute' was one letter from the project it no longer follows. The
package, module and command are now rpmroute; the freeroute command stays
as an alias, and the RPMROUTE / RPMROUTE_ORACLE_JAVA variables fall back
to the old FREEROUTE names. Version 2026.10.07. Routing is unchanged: a
PCBench board routes to a byte-identical session either way.
Copies the board (stripping its tracks unless --keep), exports the DSN
through mckicad, routes, applies the session and runs DRC with zones
refilled, counting hole problems whatever their severity. FREEROUTE and
MCK choose the builds under test.
