 * The compatibility model is as follows. The current format should be retained
6
 * for as long as possible; new fields can be added at the end of the line,
7
 * because ps/top only read as much as they know of from the start of the line.
8
 * Once fields (really) have to be removed, or the whole line becomes too big
9
 * of a mess, a completely new format string can be put in, but with an
10
 * increased PSINFO_VERSION at the beginning. That way, older ps/top copies
11
 * will not misinterpret the new fields, but rather fail cleanly.
