Might as well post a sample module... This one's the kernel symlink
manager thingie, which I wrote mainly as a test / demo thing but it can
be vaguely useful too:

http://svn.berlios.de/viewcvs/*checkout*/eclectic/trunk/modules/kernel.eclectic

Note the ebuild-like format that should be nice and easy for everyone to
get their heads around.

So what's this like from a user perspective?

ciaranm@snowdrop ~ 0 2.30 $ eclectic kernel 
Usage: eclectic kernel <action> <options>

Standard actions:
  help                      Display help text
  usage                     Display usage information
  version                   Display version information

Extra actions:
  list                      List available kernel symlink targets
  set                       Set a new kernel symlink target
  show                      Show the current kernel symlink

ciaranm@snowdrop ~ 0 2.30 $ eclectic kernel show
Current kernel symlink:
  linux-2.6.12-rc1          
ciaranm@snowdrop ~ 0 2.10 $ eclectic kernel list
Available kernel symlink targets:
  [1]   linux-2.6.10
  [2]   linux-2.6.11
  [3]   linux-2.6.11-rc5
  [4]   linux-2.6.12-rc1
ciaranm@snowdrop ~ 0 2.01 $ sudo eclectic kernel set 1
ciaranm@snowdrop ~ 0 2.01 $ eclectic kernel show
Current kernel symlink:
  linux-2.6.10              

It's all in colour, of course.

But wait, it gets sneakier. Say we install a kernel-config symlink to
eclectic. Then this will also work:

ciaranm@snowdrop ~ 0 1.50 $ kernel-config list
Available kernel symlink targets:
  [1]   linux-2.6.10
  [2]   linux-2.6.11
  [3]   linux-2.6.11-rc5
  [4]   linux-2.6.12-rc1

I added this sneaky little hack in that checks the binary name, and if
it's foo-config or foo-update, it treats it as eclectic foo [...]. So
you don't even get to whine about the stupid name :)

By the way, this could also implement GLEP 24 (consistent tool naming).
See, if you run eclectic with no arguments:

ciaranm@snowdrop ~ 0 1.36 $ eclectic 
Usage: eclectic <module name> <options>

Built-in modules:
  help                      Display a help message
  list-modules              Find and display available modules
  usage                     Display a usage message
  version                   Display version information

Extra modules:
  bashcomp                  Manage contributed bash-completion scripts
  blas                      Manage installed BLAS implementations.
  kernel                    Manage the /usr/src/linux symlink
  lapack                    Manage installed LAPACK implementations.
  mailer                    Manage the mailwrapper profiles in /etc/mail
  profile                   Manage the /etc/make.profile symlink

*shrug* it's probably full of bugs still.

I'm staying out of this one...

Oh, we have an IRC channel if you have development questions. You can
figure out the name easily enough :)
