Syntax:help;
 helptopic;Type:none
Purpose:displays online help information for topicusing the currently
set help browser. If notopicis given, the title page of the
manual is displayed.
Note:
?may be used instead ofhelp.
topiccan be an index entry of the SINGULAR manual or the
name of a (loaded) procedure which has a help section.
topicmay contain wildcard characters (i.e.,*characters).
If a (possibly "wildcarded") topiccannot be found (or
uniquely matched) a warning is displayed and no help information is
provided.
If topicis the name of a (loaded) procedure whose help
section has changed w.r.t. the help available in the manual then,
instead of displaying the respective help section of the manual in the
help browser, the "newer" help section of the procedure is simply
printed to the terminal.
The browser in which the help information is displayed can be either set
with the command-line option --browser=<browser>(see  Command line options), or with the commandsystem("--browser",
"<browser>"). Use the commandsystem("browsers");for a list of
all available browsers. See  The online help system, for more details
about help browsers.
