# Note about building Nimbus as a library:
#
# There were `wrappers`, `wrappers-static`, `libnimbus.so` and `libnimbus.a`
# target scripts here, and C and Go examples for calling the Nimbus library in
# directory `wrappers/`.  They have been removed because they only wrapped
# Whisper protocol support, which has been removed as it is obsolete.
#
# This note is kept so that anyone wanting to build Nimbus as a library or call
# from C or Go will know it has been done before.  The previous working version
# can be found in Git history.  Look for the `nimbus-eth1` commit that adds
# this comment and removes `wrappers/*`.
