This is not entirely correct.

I would like to clarify something first:
The dmd deb packages from <http://dlang.org/download.html> are "all-in-one" packages, so users has to download just one file to install everything related to dmd, and easily upgrade everything to new versions. This shouldn't be compared with the Debian repositories system, for that you have <http://d-apt.sourceforge.net/>.

On d-apt repository there are four packages related with dmd:
- "dmd-bin" - includes the compiler and other utilities. Depends on "libphobos2-dev"
- "dmd-doc" - includes the documentation with a system menu entry, and man pages.
- "libphobos2-65" - includes the runtime shared library "libphobos2.so.65.0" (real share lib) and "libphobos2.so.65" (SONAME symlink to the real lib).
- "libphobos2-dev" - includes "libphobos2.a", source modules and "libphobos2.so" (symlink to real lib. It's just for linking purposes). Depends on "dmd-bin" and "libphobos2-65"

A couple of things about "libphobos2-65":
- It's present on <http://ftp.digitalmars.com/> because shared libraries are necessaries at run-time. Thus, users can run programs compiled with dmd on computers without the compiler installed.
- Version is included on package name, allowing to install several versions at same time.

"dmd-bin", "dmd-doc" and "libphobos2-dev" conflicts "dmd".
"libphobos2-65" conflicts only "dmd" v2.065, but not other versions.

Ok, added on TODO list, in a very low priority.

This is already done on d-apt.

You're right, I'll clean up, but I don't know if everything out of "std" directory can be removed.
"etc" folder can be removed?

Thank you for your comments.
