New class to parse and replace method signatures, instead of iterating over
each class. On my machine, old technique takes 6.8 to compare Minecraft 1.4.7,
new technique: 0.5 seconds, with identical results.
The --shade-relocation/-R option causes the --srg-in mapping old class
names to be transformed with the pattern. Multiple patterns can be given,
though currently only exact prefix matches are supported.
Example:
--shade-relocation net.minecraft.server=net.minecraft.server.v1_4_R1
--shade-relocation org.bouncycastle=net.minecraft.v1_4_R1.org.bouncycastle
The mapping will be 'shaded' before being applied to the jar.
You can use these options with --srg-in 1.4.7/cb2obf.csrg to remap plugins
which depend on the version-shaded class names (aka 'vcb').
Package remaps are not generated by the jar compare, but can be added
programmatically by adding to JarMapping#packages, or in a .csrg as a
class remap but with a trailing slash, for example:
com/google/ guava10/com/google
will remap all classes in com/google/ to classes in guava10/com/google
