This documentation reminds here until it gets moved to the official documentation on http://erlang.mk/guide/.
This plugin is available by default. It adds automatic
compilation of ErlyDTL templates found in templates/*.dtl
or any subdirectory.
By default it ignores names of subdirectories and compiles
a/b/templatename.dtl into templatename_dtl.beam. To include
subdirectories names in the compiled module name add
DTL_FULL_PATH=1 into your Makefile - a/b/templatename.dtl
will be compiled into a_b_templatename_dtl.beam.
Additional ErlyDTL options can be specified as a comma-separated list
by defining the DTL_OPTS variable. Those options will be prepended
to the options specified by the plugin itself.
