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