#   ./_updateBuildTools.sh             -> update both
#   ./_updateBuildTools.sh scripts     -> only _build.sh / _build.bat
#   ./_updateBuildTools.sh publisher   -> only publisher.jar
#
# The build scripts are maintained by HL7 in
# https://github.com/HL7/ig-publisher-scripts. The copies in igs/base-<rx> are
# overwritten on every preprocessing run, so they are updated in ig-src, the
# source for the generated IGs. Run ./_preprocessMultiVersion.sh afterwards to
# propagate them to the generated IGs.
#
# The publisher.jar is placed in the parent directory of the generated IGs, so
# that all FHIR versions share a single copy.
