+"""Syntax: create_childs [-i|--input=INPUTFILE] [-o|--output=GLMFILE] [OPTIONS ...]
+
+Options
+-------
+    -P|--parents=NAME:VALUE,... specify parent property pattern to match (required)
+    -C|--childs=NAME:VALUE,...  specify child property list to assign (required)
+    -N|--names=STRING           specify object naming convention (default is '{class}_{name}')
+    -M|--modules=NAME,...       specify module names to use (defaults to those found)
+
+Description
+-----------
+
+The `create_childs` tool adds child objects to all objects that match the
+parent object pattern specified.
+
+Parent patterns and child properties as specified as a comma-separate list of
+`NAME:VALUE` strings, e.g., `class:node` or `nominal_voltage:2.4kV`. Parent
+patterns use `regex` pattern matching. Child properties may include `{NAME}` 
+format strings where `NAME` is a property of the parent object. This
+allows copying of values from the parent object. This formatting also can be
+applied to the naming string, e.g., `-N='{name}_L' to append '_L' to the
+parent object name.
+
+Example
+-------
+
+The following creates a GLM file containing a `triplex_load` objects attached
+to `triplex_node` objects with names starting as `N_` in the file `my-network.json`:
+
+~~~
+$ gridlabd create_childs -i=my-network.json -o=loads.glm -P='class:triplex_node,name:^N_' -C='class:triplex_load,nominal_voltage:{nominal_voltage},phases:{phases},constant_power_B:1.2+0.1jkVA'
