gmt5syntax — Convert old GMT script to use new 'gmt <module>' syntax
gmt5syntax old_script > new_script
gmt5syntax is a perl script that converts old-style GMT commands in, e.g., shell scripts, to the new gmt <module>-syntax. This utility is located in the tools subdirectory of the data directory. gmt --show-datadir will show the path to the latter.
