Convert the svg files to pdf/eps for a project automatically.

[Hongyi Zhao]

Currently, the latexmk can't automatically convert graphics formats
for files located under the subfolders of a project due to the
graphics package limitation of not logging the path info into the log
file.

So, I want to write a function to convert the graphic formats, say,
from svg to pdf/eps for files automatically, if necessary. Especially
when they are located under a project's subfolders.

Any hints for this job will be highly appreciated.
