all about ICPC 2013

Program comprehension is a vital software engineering and maintenance
activity. It is necessary to facilitate reuse, inspection,
maintenance, reverse engineering, reengineering, migration, and
extension of existing software systems. ICPC provides an opportunity
for researchers and industry practitioners to present and discuss both
the state of the art and the state of the practice in the general area
of program comprehension.
