20 * NOTES:
21 *
22 * The basic grammar of the file is yet another example of, humpf,
23 * design. There is is mix of context-insensitive and -sentitive
24 * stuff, which makes it rather complicated.
25 * The header definitions are all context-insensitive because they have
26 * delimited arguments, whereas the message headers are (semi-) context-
27 * sensitive and the messages themselves are, well, RFC82[12] delimited.
28 * This mixture seems to originate from the time that ms and ibm were
29 * good friends and developing os/2 according to the "compatibility"
30 * switch and reading some comments here and there.
31 *
32 * I'll ignore most of the complications and concentrate on the concept
33 * which allows me to use yacc. Basically, everything is context-
34 * insensitive now, with the exception of the message-text itself and
35 * the preceding language declaration.
