[tex-live] latex tpm dependencies

[Nguyen Thai Ngoc Duy]

Hi,
While making ebuilds for texlive in order to integrate texlive into
gentoo, I encountered geometry package depended on graphics but
geometry.tpm didn't record this dependency. In geometry.sty, there was
a line:
\RequirePackage{keyval}%
Such dependencies can be automatically discovered by grepping
\RequirePackage and find the package that contains the corresponding
file. I'm not familiar with tpm generation so I don't know how hard it
is to do that. Is it plausible to do?
