+=== Temporary region ===
+If your script needs to modify computational region, use the following functions:
+{{{
+#!python
+grass.use_temp_region()
+# now you can safely modify the region
+grass.run_command('g.region', rast='input')
+# and when you are done:
+grass.del_temp_region()
+}}}
+
+Note that changing computational region is usually not necessary and not even expected. Typically, user sets region before running the script and expects all computations to be done within this region.
