Creating graphic files only with goal grp

There are many graphic formats, like FIG, which cannot be included directly into the target format, e.g. PDF. In case of FIG and DVI, this software converts FIG files into EPS files for inclusion into DVI. This has to be done for all goals creating document output, the most versatile of which is cfg, but this section is on creating graphic files only, which is done by goal grp.

The use case is document development. If running a latex converter like lualatex and auxiliary tools like bibtex standalone on a document which contains graphics in a format which needs conversion. If graphic files are not present in a format which allows inclusion, this causes an error. This problem is solved by running goal grp before lualatex.

Also, when building with latexmk this may result in an error. It is quite[1] save if using the config file created by goal inj. But the number of runs required may be very high.

So there are cases where the goal grp makes sense.
