+#
+# * < automake-1.12 generates .h files from .yy and .ypp files, but
+# >=automake-1.12 generates .hh and .hpp files respectively. There's no
+# good way of making a project that uses C++ yacc files compatible with
+# both versions of automake. Strong work automake developers.
+#
+# * Since we're generating code from .l/.y files in a subdirectory (glcpp/)
+# we'd like the resulting generated code to also go in glcpp/ for purposes
+# of distribution. Automake gives no way to do this.
+#
+# * Since we're building multiple yacc parsers into one library (and via one
+# Makefile) we have to use per-target YFLAGS. Using per-target YFLAGS causes
+# automake to name the resulting generated code as <library-name>_filename.c.
+# Frankly, that's ugly and we don't want a libglcpp_glcpp_parser.h file.
