*   This tool reads a .ucm file, expects there to be a line in the header with
*   "File created on..." and removes the lines before and including that.
*   Then it removes lines with <icu:state> and <uconv_class> and <code_set_name>.
*   This helps comparing .ucm files with different copyright statements and
*   different state specifications.
*
*   To compile, just call a C compiler/linker with this source file.
