[tex-live] Format of README file for a package

[jfbu]

Hi 

in preparation for an update on CTAN to a package of mine, I have used
Markdown syntax in the README file

from the point of view of the TeXLive distribution and texdoc,
is it possible to name the file README.md rather than README,
or is there some implicit rule that the README should have
precisely that filename?

Can I join also README.html which would be the already converted-to
-html variant? (I will ask that also to CTAN)

and should README.html be rather packagenameReadme.html for example?

Sincerely,

Jean-Francois
