@preamble

[baptiste]

Hi,

This tool looks quite useful, but I ran into an error. I often use @preamble{"\providecommand{\baptiste}{First, Last}"} in my bib files, and have entries such as

@article{dummy,
	Author = {\baptiste and Other People},
	Journal = {Journal of things},
	Number = {1},
	Pages = {00000},
	Title = {Some title},
	Volume = {10},
	Year = {2016}}

I find it convenient because I can override the definition in a TeX file, e.g. to make my name bold,

\newcommand{\baptiste}{\textbf{First Last}}

@string seems more limited in scope and doesn't really allow this sort of partial transformation.
