Python for syntax conversion

[Gribouillis]

Here is the modified parse_file() that skips the lines before the first TABLE:

def parse_file(infile):
    parsed_file = []
    sequence = table_data_lines(infile)
    # find first line starting with TABLE:
    for lineno, line in sequence:
        if line.startswith('TABLE:'):
            break
    else:
        return parsed_file
    table_name = line[6:].strip().strip('"')
    while table_name:
        table_name = read_table(table_name, sequence, parsed_file)
    return parsed_file

It is important that you try to parse several input files in order to discover potential issues that we haven't seen yet in the parsing phase.
