   2 # HFacer.py - regenerate the Scintilla.h and SciLexer.h files from the Scintilla.iface interface
   3 # definition file.
   4 # The header files are copied to a temporary file apart from the section between a /* ++Autogenerated*/
   5 # comment and a /* --Autogenerated*/ comment which is generated by the printHFile and printLexHFile
   6 # functions. After the temporary file is created, it is copied back to the original file name.
