Just to mention one other approach, we use autoconf with macros that
will take a default but allow you to override versions of applications
making up a release. This method allows us to specify development
versions of one or more apps mixed in with released (production)
versions of others.


$ sh configure --help
...
Optional Packages:
  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
  --with-erl              e.g. /usr/pkg/bin/erl - sets path for erlc too
  --with-erl-run-top      Erlang run-time, e.g. /usr/pkg/lib/erlang
  --with-var-otp          Erlang var dir (default /var/otp)
  --with-vail-otp         Erlang install dir (default PREFIX/vail/otp)

Some influential environment variables:
  VSN         VSN for erts
  SYSTEM_VSN  SYSTEM_VSN for erts
  kernel_DIR  parent directory of ebin for kernel
  stdlib_DIR  parent directory of ebin for stdlib
  sasl_DIR    parent directory of ebin for sasl
  inets_DIR   parent directory of ebin for inets
  resource_manager_DIR
              parent directory of ebin for resource_manager
  targus_proxy_DIR
              parent directory of ebin for targus_proxy
  vaillib_DIR parent directory of ebin for vaillib
  yaws_DIR    parent directory of ebin for yaws

Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.
