+# labcomm-compiler-plugin
+
+Compiles labcomm files during the maven build lifecycle.
+
+
+## Example
+
+To use the plugin to compile the file `my_types.lc` put the following
+in your maven build file (pom.xml). You can then use the types as
+`import labcomm_gen.sample` where `sample` is the name of the
+sample(s) in the my_types.lc.
