Right now I am working on a new utility which shall replace the texdoc batch utility. The one big drawback in texdoc is that it often fails to locate package-related documentation. For example, the invocation
texdoc memoir
doesn't work because the main documentation file is named memman.pdf.
The new utility (working title: mthelp) uses the package manager to locate package-related documentation, i.e.,
mthelp memoir
opens memman.pdf for viewing.
I am still searching for a nice name.
