# Generate or regenerate source files based on comments in those files.
|
|
# May be modified in-place or a template may be generated into a complete file.
|

# Requires Python 2.7 or later
|
|
# The files are copied to a string apart from sections between a
|
|
# ++Autogenerated comment and a --Autogenerated comment which is
|
|
# generated by the CopyWithInsertion function. After the whole string is
|
|
# instantiated, it is compared with the target file and if different the file
|
|
# is rewritten.
