[Pkg-texlive-maint] viewer for texdoc

[Jörg Sommer]

Hi,

texdoc requests viewers for the found documents. Is it possible that
texdoc looks for some different viewers. For example, the default pdf
viewer is acroread, but I have it not installed. I use xpdf. texdoc could
check for acroread and then for xpdf and than fall back to see (from
mime-support)

BTW: It would be nice, if texlive-base-bin would insert any entry in the
mime database (update-mime from mime-support)

Bye, Jörg.
