\\********************** FORMAT OF THIS FILE : ***************************
\\ 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 ?\).
