GMT passes information about previous GMT commands onto later
GMT commands via a hidden file (.gmtcommands).  To avoid that
this file is updated by more than one program at the same time
(e.g., when connecting two or more GMT programs with pipes) we
use POSIX advisory file locking on the file.  Apparently, some
versions of the Network File System (NFS) have not implemented
file locking properly.  We know this is the case with Linux
pre-2.4 kernels when mounting NFS disks from a Unix server.
If this is your case you should turn file locking OFF.

Normally, all coastline files are installed in ./GMT${VERSION}/share.
However, you can also place some of them in separate directories.
These dirs must exist or you must have write permission to make them.
If alternate directories are specified then a coastline.conf file will
be kept in ./GMT${VERSION}/share to contain the names of these directories.
NOTE:  Do not append the final /share as that is done automatically!

install_gmt - Automatic installation of GMT ${VERSION}

GMT is installed in the background following the gathering
of installation parameters.  These parameters are obtained
in one of two ways:

(1) Via Internet: You may compose a parameter file using
    the form on the GMT home page (see the installation
    link under gmt.soest.hawaii.edu) and save the result
    of your request to a parameter file on your hard disk.
2)  Interactively: You may direct this script to start an
    interactive session which gathers information from you
    via a question-and-answer exchange and then saves your
    answers to a parameter file on your hard disk.
    
The parameter file is then passed on to the next stage which
carries out the installation without further interruptions.

Thus, two forms of the command are recognized:

install_gmt parameterfile [ &> logfile]  (for background install)
install_gmt [ -n ] [ &> logfile]	 (for interactive install)

The option -n means do NOT install, just gather the parameters.
Of course, there is also

      install_gmt.s -h			    (to display this message)
