20: .SH DESCRIPTION
21: Initiate a session with the
22: .I maple
23: symbolic algebraic program.
24: Expressions are read from standard input and the results are produced
25: in the standard output file as soon as each input expression has been
26: read.
27: Maple has the ability to algebraically manipulate unbounded integers,
28: exact rational numbers, real numbers with arbitrary precision, symbolic
29: formulae, polynomials, sets, lists, and equations.
30: It can solve systems of equations, differentiate formulae, and integrate
31: formulae.
32: In the following example from a Maple session, Maple's output
33: is shown to the right of the input expressions.

90: If there is a system-wide maple initialization file with the name
91: .I init
92: under the src subdirectory of the Maple library, then this file
93: is read before the session starts.
94: In addition, if there is a maple initialization file named
95: .I .mapleinit
96: in the user's home directory, this file is read next.
97: If the \fI\-s\fR (suppress initialization)
98: option is specified, Maple will forego reading
99: any initialization file when initiating a session.
100:
101:
102: If the
103: .I \-b
104: (library) option is used,
105: then
106: .I pathname
107: should be the pathname of a directory which contains the Maple library.
108: This is used to initialize the value of the Maple variable `libname'.
109: By default, `libname' is initialized with the pathname /u/maple/lib.
110: Some sites may install a maple shell script which uses the \fI\-b\fR
111: option to redefine the library pathname to be whatever is appropriate
112: for those sites, e.g.,
113: .nf
114: maple \-b /usr/public/waterloo/maple/lib $*
115: .fi
116:
117: The \fI\-q\fR (quiet) option will suppress the printing of Maple's
118: startup logo, various informational messages (words used messages
119: and garbage collection messages), and the signoff message.
120: Maple is better suited for use as a filter when these messages are
121: suppressed.

140: At Waterloo, there is the newsgroup uw.maple which contains broadcasts
141: and discussions which would be of interest to general Maple users.
142: You should subscribe to this newsgroup if you intend to use Maple in
143: more than just a casual manner.
144: Users are encouraged to post their questions regarding Maple to this
145: newsgroup if they feel that their enquiries are of a general nature.
146: Replies will be posted to the newsgroup for all to see.
147: If you have a question that you think is of a very specific nature and
148: not of interest to others, you may send a mail message to
149: maple_help@watmum.
