vp-fitrename - command line tool to rename fits
vp-fitrename allows for command line renaming of fits.
To do so, call vp-fitrename with a path to the original fit and
the requested new fit. The optional flags allow for preserving
a copy of the original fit and also to change fits in the NNPDF
results directory.
