.SH SYNOPSIS
.sp
\fBgmtwhich\fP \fIfiles\fP [  \fB\-A\fP ] [  \fB\-C\fP ] [  \fB\-D\fP ] [  \fB\-G\fP ] [  \fB\-V\fP[\fIlevel\fP] ]
.sp
\fBNote:\fP No space is allowed between the option flag and the associated arguments.
.SH DESCRIPTION
.sp
\fBgmtwhich\fP reports the full paths to the files given on the command
line. We look for the file in (1) the current directory,
(2) in $GMT_USERDIR (if defined), (3) in $GMT_DATADIR (if defined), or
(4) in $GMT_CACHEDIR (if defined). If
found we print the full path name to the file, just the directory (see
\fB\-D\fP), or a confirmation (see \fB\-C\fP). The $GMT_USERDIR and
$GMT_DATADIR environment variables can be colon\-separated list of
directories, and we search recursively down any directory that ends with
/ (i.e., /export/data is a single directory whereas /export/data/ will
be searched recursively.)
