The idea is use easy labels in the \cite of the latex file and the use the scripts

Inside the LaTeX document you can use arxiv numbers or journal-like references, then
$ texkey
to convert to inspire texkeys and the use to
$ bibtexspires
and, optionally
$ bblspires
Check the help in each script for further information
