[requirements skipped]

I would go autoconf/automake, since this solution is pretty powerful and
configurable and may solve your requirements nicely. I know this, because
it solves build/install requirements of even more complex projects.

Basically, you want to install standard things, like:

  --bindir      defaults to ${prefix}/bin     - executables
  --mandir      defaults to ${prefix}/man     - man pages
  --datadir     defaults to ${prefix}/share   - perl, wml stuff

Where --prefix defaults to /usr/local, but may be anything, /usr, /opt.
Several different things may be installed relatively to $datadir, like:

  ${datadir}/quadpres/perllib  - Perl modules, in @INC
  ${datadir}/quadpres/wml      - WML stuff if needed
  ${datadir}/quadpres/scripts  - Perl scripts that are not in $bindir

Here is how to easily manage the last 3 directories given you already
have the same structure in your source tree. Create, for example, this
perllib/Makefile.am file:

  SUBDIRS = QuadPres
  configdir = @QUADPRES_PERLLIB_DIR@
  config_DATA = QuadPres.pm
  EXTRA_DIST = $(config_DATA)

Each subdir is similar, for example perllib/QuadPres/Makefile.am may be:

  SUBDIRS = OneMoreLevel1 OneMoreLevel2
  configdir = @QUADPRES_PERLLIB_DIR@/QuadPres
  config_DATA = Module1.pm Module2.pm
  EXTRA_DIST = $(config_DATA)

And here is how bin/quadpres.in may look like (that the main quadpres
script is automatically generated from by ./configure):

    our $prefix = '@prefix@';
    our $bindir = "@bindir@";
    our $datadir = "@datadir@";
    our $perllib_dir = "@QUADPRES_PERLLIB_DIR@";
  use lib $perllib_dir;
  use QuadPres::Module1;

Now, add these lines to configure.in (or configure.ac):




These are mostly the key things needed for quadpres or a similar project.
Of course, this assumes some initial experience with autoconf/automake.
Finally, there is no built-in support for --docdir, but you wrote it is
not critical for you; and you may always add a custom --with-docdir
option to ./configure if needed.
