1.20 Start-up (initialization)

When gnuplot is run, it first looks for a system-wide initialization file named `gnuplotrc`. The location of this file is determined when the program is built and is reported by loadpath. The program then looks in the user's HOME directory for a file called `.gnuplot` on Unix-like systems or `GNUPLOT.INI` on other systems. (Windows and OS/2 will look for it in the directory named in the environment variable `GNUPLOT`; Windows will use `USERPROFILE` if GNUPLOT is not defined). Note: The program can be configured to look first in the current directory, but this is not recommended because it is bad security practice.
