help, ? - output of a help text

Calling sequence:
help("keyword")
?keyword

Parameter:

keyword   --  keyword

Summary:

help("keyword") outputs a help text with information about the keyword
keyword.  The exact form of the output depends on the computer.  In
the terminal version information is output as ASCII text.  In xmupad , the
OpenWindows interface to MuPAD, the user can obtain information from
the hypertexton-line documentation. See also page ??.

Instead of help("keyword"), the user can also simply enter ?keyword. However,
the ? command is not a MuPAD function and therefore cannot be used in
expressions. It can only be entered interactively and in a seperate line. Note
that neither the keyword need be set in quotation marks nor the command
closed with a semicolon.

The keyword can contain the "wildcards" ?  and * :  ?  stands for any or
a missing character, * stands for any (also an empty) series of characters.

?*normal* returns normal groebner::normalf linalg::normalize stats::normal
for example.

In the terminal version the user only has access to a short description of
system functions and system variables. The hypertext on-line documentation
also includes information about types and control structures, e.g. if or for.
The command anames(0); gives an overview of the system functions and ?*
gives an overview of the help pages available in MuPAD.

Commands must be closed with a semicolon or colon. MuPAD executes this
command when the user presses the <Return> or <Enter>key. The command
can also be more than one line long. More than one command can be entered
in one line if each command is ended with a semicolon. Two exceptions to
this are the ? and ! commands. quit ends MuPAD.
