Initial revision

/*  .gprc   (c) K.B. version 2.14 (11 June 1999)
 * 
 * SAMPLE GP INIT FILE.
 *
 * Customize (by uncommenting and modifying the relevant lines) and put in
 * $HOME/.gprc (or $GPRC) or /etc/gprc. Syntax explained at the end. */

\\ read "lib/gpalias"
/* Read lib/gpalias BEFORE gp prompts you for commands.
 * The file contains some standard abbreviations (correct the path!!!) */

\\ secure = 1
/* Disable commands system() and extern(). These commands are dangerous
 * since they allow scripts to execute arbitrary Unix commands */

\\ compatible = 0
/* CAUTION: scripts written in the old (1.x) syntax WILL NOT WORK AS BEFORE.
 * If compatible>1, the OLD functions are the ONLY ONES known to gp, save
 * for default() itself */

\\ path = ".:~:~/gpdir"
/* List of directories where gp will look for scripts (separated by ':',
 * use "\:" to insert a real ":"). The ~ notation may not be available on
 * your system */

/* Set gp prompt. % is used for macros related to the time of day [back to
 * the shell prompt, try "man strftime"]. Example: %R = time of day in the
 * form HH:MM. Characters can be escaped UNIX-style using '\', e.g \e = <ESC>
 *
 * Above, the first escape sequence sets a bold font, the second restores
 * the original (so we get a bold "gp"), and we prefix by the time of day
 *
 * CAUTION1: If you have escape sequences in your prompt (as above) and use
 * readline, you will get display bugs. With a recent enough readline, you
 * can work around those by bracing non-visible characters between ^A/^B
 * pairs (see manual), like this:
 * 
 * #if READL prompt = "(%R) 
\e[1mgp
\e[m > "
 *                          ^^_____^^ brace the "set bold" sequence \e[1m
 *
 * CAUTION2: If you plan to use gp under emacs, do not tamper with the prompt
 * variable UNLESS you also set correctly the gp-prompt-pattern regexp in
 * your .emacs. For instance, if to use:
 *
 * #if EMACS prompt = "(%R) gp > "
 *
 * add the following two lines in your .emacs:
 *
 * (setq gp-prompt-pattern
 *  (concat "^([0-9][0-9]:[0-9][0-9]) gp > [\C-j\t ]*\\|" gp-prompt-pattern))

\\ clear background:
\\   #ifnot EMACS colors = "9, 5, no, no, 4, 1, 2"
\\ dark background:
\\   #ifnot EMACS colors = "9, 1, no, no, 6, 1, 2"
/* If your terminal supports color. These are suggested values that don't
 * look too bad with the colormap provided with the distribution (under
 * emacs you have to customize colors using the Menu Bar). */

\\ Extended help options (don't interact well with emacs):
\\ Don't use TeX + xdvi, but outputs formatted help in GP window:
\\   #ifnot EMACS help = "/usr/local/bin/gphelp -detex"
\\ Same, using colors:
\\   #ifnot EMACS help = "/usr/local/bin/gphelp -detex -ch 4 -cb 0 -cu 2"

\\ Stack size : 10MB.
\\ parisize = 10 000 000

\\ Biggest precomputed prime
\\ primelimit = 1 000 000

\\ Set timer on
\\ timer = 1

\\ Set logfile name and enable logging.
\\ Uncommenting the next two lines produces a different logfile each day:
\\ logfile = "~/tmp/pari-%d.%m"
\\ log = 1

\\ Output for postscript-producing gp commands.
\\ psfile = "~/tmp/pari.ps"

\\*****************************    FORMAT :     ***************************
\\  Lines starting with '\\' and between '/*' '*/' pairs are comments
\\  Blank lines are ignored
\\  Line starting with #if KEYWORD is read iff KEYWORD is TRUE
\\  Currently recognized keywords:
\\    EMACS  are we running under emacs?
\\    READL  is readline available?
\\
\\  This file should be put in $HOME/.gprc or /etc/gprc and contain:
\\  * references to gp scripts that are to be run BEFORE the first gp prompt.
\\
\\    Syntax: read "filename"  (quotes are mandatory. ~ syntax allowed)
\\
\\  * variable definitions (so-called "environment variables" in the sequel)
\\
\\   Definitions are overruled by command line switches. For instance
\\     invoking gp -s 100 will set environment variable stacksize to 100 (not
\\     a very bright thing to do by the way), regardless of what is in .gprc
\\
\\    Syntax: variable name = value
\\
\\  Environment variables which are not set here assume default values in gp.
\\  Can be changed under GP using default(), or keyboard shortcuts (see ?\).
