libpsych-java - 5.0.2-3 main

ruby-psych is a YAML parser and emitter. Psych leverages libyaml for its
YAML parsing and emitting capabilities. In addition to wrapping
libyaml, Psych also knows how to serialize and de-serialize most Ruby
objects to and from the YAML format.
.
Psych has been included with the main Ruby implementation since 1.9.2,
and is the default YAML parser from 1.9.3 and beyond.
.
libpsych-java ships the Java extension to improve performance for Ruby
implementations running in the JVM, like jruby.
