+The default configuration generated by 'guard init compass' looks like this

+bc. guard 'compass' do
+  watch('^src/(.*)\.s[ac]ss')

+
+the compass guard accept two options:
+
+ * :workdir: all compass relative path will be computed from there
+ * :configuration_file: relative or absolute path to your compass configuration file
+
+By default, the working directory is the folder where you run guard in and
+the configuration_file is computed by compass
