371   .BR PICTURE
372   This is the root name of the output picture file(s).
373   This name will have appended the view identifier (or a number if no
374 < id was used) and a ".pic" suffix.
374 > id was used) and a ".hdr" suffix.
375   If a picture corresponding to a specific view exists and is not out
376   of date with respect to the given octree, it will not be
377   re-rendered.
# Line 472 | Line 472 | There is no default value for this variable.
472   .BR oconv
473   This variable may be used to specify special options to
474   .I oconv.
475 + If the first word of the first instance of this variable is not an option,
476 + it will be used in place of the default command path, "oconv".

647 + You cannot run more than one

649 + process at a time on the same input file,
650 + as the second process will attempt to recover the output files
651 + of the first process, damaging the results.
652 + The exceptions to this are running interactively via the

658   Incremental building of octrees is not supported as it would add
