! 15: .SH DESCRIPTION
! 16: Invokes the PARI-GP calculator. GP is an advanced programmable calculator,
! 17: which computes symbolically as long as possible, numerically where needed,
! 18: and contains a wealth of number-theoretic functions (elliptic curves, class
! 19: field theory...). Its basic data types are
! 20: .TP
! 21: numbers
! 22: integers, real numbers, exact rational numbers, algebraic numbers,
! 23: .BR p "-adic numbers,"
! 24: complex numbers,
! 25: .TP
! 26: modular integers
! 27: integers modulo
! 28: .BR n ,
! 29: .TP
! 30: polynomials
! 31: and rational functions,
! 32: .TP
! 33: power series,
! 34: .TP
! 35: binary quadratic forms,
! 36: .TP
! 37: matrices, vectors,
! 38: and lists,
! 39: .TP
! 40: character strings,
! 41: .PP
! 42: and recursive combinations of these.
! 43:
! 44: .SH OPTIONS
! 45: A numeric argument to the following options can be followed by a
! 46: .B k
! 47: or a
! 48: .B M
! 49: at the user's convenience. In that case the argument is multiplied by 1000
! 50: or 1000000 respectively. The following command line options are available:
! 51: .TP
! 52: .B \-emacs
! 53: GP can be run in an
! 54: .I Emacs
! 55: shell (see GP User's manual for details). This flag is then required for
! 56: smooth interaction with the relevant
! 57: .I Emacs
! 58: package (pari.el). It is set automatically by the pari.el package, and will
! 59: produce nice display oddities if you set it outside of an
! 60: .I Emacs
! 61: session.
! 62: .TP
! 63: .B \-f
! 64: Fast start (or factory settings). Do not read
! 65: .B .gprc
! 66: (see below) upon startup.
! 67: .TP
! 68: .B \-q
! 69: Quiet mode. Don't print headers or history numbers, don't say goodbye.
! 70: .TP
! 71: .BI \-p " primelimit"
! 72: Upon startup, GP computes a table of small primes used in most
! 73: number-theoretic applications. If
! 74: .I primelimit
! 75: is set here, include primes up to that bound instead of the default.
! 76: Unreasonably high values will considerably increase startup time. Exceedingly
! 77: small values will cause some number-theoretic functions to fail with the
! 78: message "not enough precomputed primes".
! 79: .TP
! 80: .BI \-s " stacksize"
! 81: Size of GP internal stack allocated on startup. When GP runs out of space, it
! 82: interrupts the current computation and raises a
! 83: .BI "stack overflow"
! 84: exception. If this occurs frequently (especially if you make heavy use
! 85: of linear algebra), start with a bigger stack. The stack size can also be
! 86: increased from within GP, using
! 87: .B default(parisize, ...)
! 88: ; it may be convenient to set
! 89: .B stacksize
! 90: from your
! 91: .B .gprc
! 92: Note that computations with a
! 93: .B smaller
! 94: stack may be more efficient due to better data locality. Sensible
! 95: computations should need less than 20MB.
! 96:
! 97: .TP
! 98: .B \-test
! 99: run GP in test mode: suppress printing of history numbers and wrap long
! 100: output lines (to get readable diff output). For benches only.
! 101: .SH USE
! 102: .TP
! 103: .B ?
! 104: to get online help.
! 105: .TP
! 106: .B ??
! 107: to get extended online help (more precisely, to call the external help
! 108: program,
! 109: .B gphelp
! 110: by default)
! 111: .TP
! 112: .B quit
! 113: (or \\q), or
! 114: .B EOF
! 115: (Ctrl-D) to quit
! 116: .BR gp .
! 117: .PP
! 118: The following works only when gp was linked with GNU
! 119: .IR readline
! 120: library:
! 121: .TP
! 122: arrow keys
! 123: for editing and viewing the input history.
! 124: .TP

! 235: If you find a bug, you should report it. First make sure that it really
! 236: is a bug and that it appears in recent versions of the package.
! 237: Then you can actually mail your bug report (make it short
! 238: and easily reproducible if possible), including the header
! 239: .B gp
! 240: displays on startup, to the
! 241: .IR pari-dev
! 242: mailing list (preferably) or to
! 243: .IR pari@math.u-bordeaux.fr .
! 244: Fixes are welcome too !
! 245:
! 246: .SH TRIVIA
! 247: Despite the leading G, GP has nothing to do with GNU. The first version was
! 248: originally called GPC, for Great Programmable Calculator. For some reason,
! 249: the trailing C was eventually dropped.
! 250:
! 251: PARI has nothing to do with the French capital. The name is a pun about the
! 252: project's early stages when the authors started to implement a library for
! 253: "Pascal ARIthmetic" in the PASCAL programming language (they quickly
! 254: switched to C).
! 255:
! 256: For the benefit of non-native French speakers, here's a slightly expanded
! 257: explanation:
! 258: .B Blaise Pascal
! 259: (1623-1662) was a famous French mathematician and philosopher who was one
! 260: of the founders of probability and devised one of the first "arithmetic
! 261: machines". He once proposed the following "proof" of the existence of God
! 262: for the unbelievers: whether He exists or not I lose nothing by believing
! 263: in Him, whereas if He does and I misbehave... This is the so-called "pari
! 264: de Pascal" (Pascal's bet).
! 265:
! 266: Note that PARI also means "fairy" in Persian.
! 267:
! 268: .SH AUTHORS
! 269: PARI was originally written by Christian Batut, Dominique Bernardi, Henri
! 270: Cohen, and Michel Olivier in Laboratoire A2X (Universite Bordeaux I, France),
! 271: and was maintained by Henri Cohen up to version 1.39.15, and by Karim Belabas
! 272: since then.
! 273:
! 274: A great number of people have contributed to the successive improvements
! 275: which eventually resulted in the present version. See the AUTHORS file in
! 276: the distribution.
