If -netcdf was used previously, read from the netCDF file
X_var and Y_var variables and create a set.
If X_var is "null" then load the index of Y to X.
This option is present only if the netCDF support was compiled in

A flag (0 or 1) and a file name which determine whether a FFT should use

In many cases, when Grace needs to access a file given with a

The following files are of a special importance:
- init file loaded upon start up.
- the default template, loaded whenever a new project is started.
- the file responsible for font configuration.
