+#
+# rebar3 is a tool which tries to resolve dependencies itself which is by
+# cloning remote git repositories. Dependant projects are usually expected to
+# be in sub-directory 'deps' rather than looking at system Erlang lib
+# directory. Projects relying on rebar3 usually don't have 'install' make
+# targets. The eclass workarounds some of these problems. It handles
+# installation in a generic way for Erlang/OTP structured projects.
