# This is a version of BCEL that has been modified by the findbugs team.  They
# added some new functionality and also did some performance optimizations of
# the base code.  I am not producing a new manual, since we already have a
# bcel-manual package and the findbugs team did not patch the manual.  However,
# the javadoc package is necessary to show the changes in the API created by
# the findbug team's work.

%description
This is a version of Apache's Byte Code Engineering Library (BCEL) that has
been modified by the findbugs developers.  The modifications add some new
functionality, and also introduce a number of performance optimizations to
address findbugs performance problems.  Some of the performance optimizations
induce API changes, so this version of BCEL is not compatible with the vanilla
upstream version.
