+# - Precompilation of Vala/Genie source files into C sources
+# Makes use of the parallel build ability introduced in Vala 0.11. Derived
+# from a similar module by Jakob Westhoff and the original GNU Make rules.
+# Might be a bit oversimplified.
+#
+# This module defines three functions. The first one:
+#
+#   vala_init (id
+#     [DIRECTORY dir]          - Output directory (binary dir by default)
+#     [PACKAGES package...]    - Package dependencies
+#     [OPTIONS option...]      - Extra valac options
+#     [CUSTOM_VAPIS file...])  - Custom vapi files to include in the build
+#     [DEPENDS targets...])    - Extra dependencies for code generation
+#
+# initializes a single precompilation unit using the given arguments.
+# You can put files into it via the following function:
+#
+#   vala_add (id source.vala
+#     [DEPENDS source...])     - Vala/Genie source or .vapi dependencies
+#
+# Finally retrieve paths for generated C files by calling:
+#
+#   vala_finish (id
+#     [SOURCES sources_var]          - Input Vala/Genie sources
+#     [OUTPUTS outputs_var]          - Output C sources
+#     [GENERATE_HEADER id.h          - Generate id.h and id_internal.h
+#       [GENERATE_VAPI id.vapi]      - Generate a vapi file
+#       [GENERATE_SYMBOLS id.def]])  - Generate a list of public symbols
