The boost/ subdirectory would look like this:


This has twice the amount of directory entries than the
current scheme under libs/. We currently have 21 subdirectories
under libs/, and I expect that number to grow. I would
prefer the number of subdirectory entries in libs/ (or boost/) to
grow with n and not with 2*n.

I do think that splitting large headers into smaller parts and
also providing an "all-in-all" header is a good idea. (I need to
do that with my random number library.)

Probably we should leave the idea that the distributed boost directory
structure can be used as-is and start having a minimal install
procedure. As a first step until we get a decent build system,
we could have a script which copies (or symlinks) all *.hpp files
from each library's include/ subdirectory to the boost/ include
directory. Probably python is the appropriate tool for that.

Note that we already have several libraries whose object files
need to be linked in (i.e. are not headers-only), so an installation
step is necessary anyway, in general.

If we would like to keep the current contents of the boost/
directory, Beman could run the copy script before creating the
release .zip file. People using the CVS version are considered
more knowledgeable and thus can call the script themselves.
