[darcs-users] Separating the user manual and code

Briefly: I have a soft spot for the literate Haskell as user's manual
approach, but I also think that Trent is probably right on this one.
This is part of a recent darcs trend in re-evaluating and simplifying
our infrastructure. We want to make it easier for people to contribute.

A third argument is that the user's manual serves as code documentation
for hackers. It gives us a "feel" for where we are in the code. On the
other hand, I suspect I am the only one here who really feels this way,
and that other developers are more distracted by the blobs of LaTeX than
Below are my favourite arguments from Trent's list for separating out
the user's manual:

I find this very convincing.

The user's manual is a bit of a tangle with the
current approach. Simpler is simpler.

Actually, even if we do not separate the manual, we should probably push
for all the API-style documentation to be haddocks. Literate Haskell
should probably only be used for user's manual and explaning theory at

I concede that it probably will be a relief to have just straight
Haskell in Vim.
Anyway, if you are willing to do the work and if you are willing to
commit to taking charge of the user's documentation (with the usual
right to delegate of course!), then I will enthusiastically support
the move (as long as we do it carefully).
