I think this could better be added to the code.scm module rather than
getting its own module.  What do you think?

Please use “mirror://sourceforge...” if possible.

This line is too long.  I’m using fci-mode in Emacs to draw a line at
the position of the fill column, so it’s easy to tell if lines are too
long.

This line is also quite a bit too long.  You could easily break this up.

This synopsis is also a tad too long.

Please use two spaces between sentences.  Also, the first sentence
fragment should be a full sentence, such as

   “CScope is a tool for browsing source code...”

not

   “A tool for browsing source code.”

(I should say that to me it’s not obvious what this tool actually does.
Is it something like ctags?)

Okay.
