+"""Python program to make autocorrection_data.h.
+
+This program reads "autocorrection_dict.txt" and generates a C source file
+"autocorrection_data.h" with a serialized trie embedded as an array. Run this
+program without arguments like
+
+$ python3 make_autocorrection_data.py
+
+Or to read from a different typo dict file, pass it as the first argument like
+
+$ python3 make_autocorrection_data.py dict.txt
+
+Each line of the dict file defines one typo and its correction with the syntax
+"typo -> correction". Blank lines or lines starting with '#' are ignored.
+Example:
+
+  :thier        -> their
+  fitler        -> filter
+  lenght        -> length
+  ouput         -> output
+  widht         -> width
+
