After CL-ARROWZ (#1495), please add TRACE-DB, and the SOFTWARE-EVOLUTION-LIBRARY (SEL). The later relies on the two former projects.
TRACE-DB is a tool for writing, reading, storing, and searching of program traces (source and binary).

SEL enables the programmatic modification and evaluation of software. See the manual for more information.

Many thanks!
