+Scons Unity Build Generator
+
+Provides several generators for SCons to combine multiple source files into a bigger
+one to reduce compilation time, so called "unity builds". This is achieved by generating
+unity source files which in term include the actual source files and compile them using
+one of the existing SCons builders.
+
+Usage
+-----
+In order to use this, just place it inside your `site_scons/site_tools` folder, enable it by
+adding "unity_build" to the tools when constructing your Environment and replace invocations
+of the Program/Library/SharedLibrary/StaticLibrary builders with their Unity... counterpart:
+
+env = Environment(tools = ['default', 'unity_build'])
+
+source_files = ...
+
+env.UnityProgram(
+    target = 'my_program',
+    source = source_files,
+    ...
+)
+
+The tool will generate an amount of unity source files and invoke the Program builder on these,
+forwarding any other arguments you passed.
+
+Other Options
+------------
+You can control the behaviour of the builder using several Environment options:
+env['UNITY_CACHE_DIR'] = '.unity' # Directory where the unity sources are stored.
+                                  # can be either a string or a Dir() node.
+env['UNITY_MAX_SOURCES'] = 15     # Maximum number of source files per unity file.
+env['UNITY_MIN_FILES'] = env.GetOption('num_jobs')
+                                  # Minimum number of unity files to generate (if possible).
+                                  # Defaults to the number of jobs passed to SCons.
+env['UNITY_DISABLE'] = False      # Set to True to completely disable unity builds. The commands
+                                  # will simply pass through their options to the regular builders.
+
+Additionally any generator can be passed a `cache_dir` to overwrite the value from the Environment.
