.SH NAME
gmtset \- To change individual \fBGMT\fP default parameters
.SH SYNOPSIS
\fBgmtset\fP [ \fB\-G\fP\fIdefaultsfile\fP ] PARAMETER1 [=] \fIvalue1\fP PARAMETER2 [=] \fIvalue2\fP PARAMETER3 [=] \fIvalue3\fP ...
.SH DESCRIPTION
\fBgmtset\fP will adjust individual \fBGMT\fP defaults settings in the current directory's \.gmtdefaults4\"'
file.  If no such file exists one will be created.  The main purpose of \fBgmtset\fP is
temporarily to change certain parameters inside a shell script, e.g., set the dots-per-inch
to 600, run the script, and reset to 300 dpi.  Optionally, you can specify one or more temporary changes
directly on any \fBGMT\fP command line with the syntax \fB\-\-PARAMETER\fP=\fIvalue\fP; such changes are
only in effect for that command and do not permanently change the default settings on disk.
.TP
PARAMETER \fIvalue\fP
Provide one or several pairs of parameter/value combinations that you want to modify.  For a
complete listing of available parameters and their meaning, see the \fBgmtdefaults\fP man page.
