# Modules batik-rasterizer-ext and batik-squiggle-ext, upstream puts their jar files in the extensions
# directory, see batik-extension/src/main/resources/org/apache/batik/extensions/README.txt
# We comment them out but keep them in the mudules list for later.
# The same for batik-test-old which depends on fop-transcoder-allinone which itself depends on batik.
# We also don't build batik-shared-resources since we install those resources on global scope.
# And we don't build batik-all. Instead we install the modules.
# BATIK_MODULES is the "Reactor Build Order" extracted from the output of "mvn dependency:tree":
