+# Compile vala files to their c equivalents for further processing. 
+#
+# The "vala_precompile" macro takes care of calling the valac executable on the
+# given source to produce c files which can then be processed further using
+# default cmake functions.
+# 
+# The first parameter provided is a variable, which will be filled with a list
+# of c files outputted by the vala compiler. This list can than be used in
+# conjuction with functions like "add_executable" or others to create the
+# neccessary compile rules with CMake.
+# 
+# The initial variable is followed by a list of .vala files to be compiled.
+# Please take care to add every vala file belonging to the currently compiled
+# project or library as Vala will otherwise not be able to resolve all
+# dependencies.
+# 
+# The following sections may be specified afterwards to provide certain options
+# to the vala compiler:
+# 
+# PACKAGES
+#   A list of vala packages/libraries to be used during the compile cycle. The
+#   package names are exactly the same, as they would be passed to the valac
+#   "--pkg=" option.
+# 
+# OPTIONS
+#   A list of optional options to be passed to the valac executable. This can be
+#   used to pass "--thread" for example to enable multi-threading support.
+#
+# CUSTOM_VAPIS
+#   A list of custom vapi files to be included for compilation. This can be
+#   useful to include freshly created vala libraries without having to install
+#   them in the system.
+#
+# GENERATE_VAPI
+#   Pass all the needed flags to the compiler to create an internal vapi for
+#   the compiled library. The provided name will be used for this and a
+#   <provided_name>.vapi file will be created.
+# 
+# GENERATE_HEADER
+#   Let the compiler generate a header file for the compiled code. There will
+#   be a header file as well as an internal header file being generated called
+#   <provided_name>.h and <provided_name>_internal.h
+#
+# The following call is a simple example to the vala_precompile macro showing
+# an example to every of the optional sections:
+#
+#   vala_precompile(VALA_C
+#       source1.vala
+#       source2.vala
+#       source3.vala
+#   PACKAGES
+#       gtk+-2.0
+#       gio-1.0
+#       posix
+#   DIRECTORY
+#       gen
+#   OPTIONS
+#       --thread
+#   CUSTOM_VAPIS
+#       some_vapi.vapi
+#   GENERATE_VAPI
+#       myvapi
+#   GENERATE_HEADER
+#       myheader
+#   )
+#
+# Most important is the variable VALA_C which will contain all the generated c
+# file names after the call.
