I am reorganizing my courses, consolidating many short files into longer
ones. So, for instance, I have a directory like:

✗ ls Assignments

ClassProjectGuidelines.org
course-blog.org
essay-assignment.org
ProjectProposal.org
STA-01-CSS.org
STA-02-wordpress-themes.org
STA-03-Foundation.org
STA-04-maps.org

I'd like to turn this into Assignments.org, with a structure like this:

* ClassProjectGuidelines.org
* course-blog.org
* essay-assignment.org
* ProjectProposal.org
* STA-01-CSS.org
* STA-02-wordpress-themes.org
* STA-03-Foundation.org
* STA-04-maps.org

It's sort of the reverse of Marcin's one-to-many export issue as described
in another thread.  Best ways to accomplish this? thx,
