NOTE:
  - ASSUME, SIDE EFFECTS, KEYWORDS, and SEE ALSO are optional. No help string is required for static procedures.
  - EXAMPLE: refers to the example section of the procedure. In a SINGULAR session, the example will be carried out upon entering `example <proc_name>;` if the procedure is loaded from a file by the `LIB` or `load` command (see LIB and see load ). No example section is allowed if the procedure is defined interactively.
  - See Typesetting of help and info strings for help strings in the SINGULAR documentation.
  - See the example in Procedures in a library for an illustration.
