[Docutils-develop] [docutils:feature-requests] #88 Unify Docutils CLI tools into `docutils-cli`

[engelbert g. <gr...@us...>]

working on the commandline means tipping less by using completion

if i type rstTABTAB the list of all writers shows up 
if there is only docutils-cli i have to read the documentation.
if there happens to be a new writer with rst.... i will be notified by the completion result,
if there is only docutils-cli i have to read the documentation.

of course new readers wont show up for rstTABTAB

This is a tracker issue for this, and to allow discussion. 

I'll briefly re-outline my argument to (eventually) drop the `rst*` front-end tools, and only export `docutils-cli` (or `python -m docutils`). 

> I think a single front-end tool significantly simplifies a lot of things -- the docutils-cli wrapper is not complex, which gives it significant points in favour in my book.

> Most usage of Docutils today is programmatic, and not via the command line tools (see the table at the bottom of this post - it shows all the projects that have a full dependency on Docutils with over 500k downloads in the last month. Of those 8, none use the command line tools)

> I also suspect (although the data does not exist) that most command line uses of the Docutils tools will be rst2html(5). This is already the default in docutils-cli, so it is a drop-in replacement.

> ...

>  My proposal isn't to remove them *\[the rst2 front-end tools\]* with no recourse, but to deprecate over a period of time, clearly marking identical drop-in commands at runtime to affected users. ... We cannot know how many people would be affected with local random scripts, but it is a two-second change.

> Many users will also run with old or pinned versions of Docutils, and part of updating is seeing the changelog. If Debian or other redistributors already make changes, they could decide to keep shell aliases from rst2* to the new docutils-cli based invocations.
