# Scamper Tools
# Scamper Python Tools
Scamper is a scalable, efficient, and feature-rich Internet packet
prober from CAIDA (http://www.caida.org/tools/measurement/scamper/).
Scamper is written in C and stores data in a binary "warts" format.

These tools replicate the functionality of scamper's utilities by
providing native python implementations. The following files
