Generic options:

Supported options:
  --enable-deps   enable dependency tracking for workspace    [default=no]

Workspace Bootstrapping
-----------------------
    Bootstrapping a workspace causes all files necessary for
    maintainers to build ACE or TAO to be generated.

    Enabling dependency tracking via the \`--enable-deps' option causes
    GNU Automake to generate dependency tracking rules in generated
    Makefile.in files.  Currently those dependency tracking rules only
    work with GNU C++, which is why dependency tracking is disabled by
    default.

Release Bootstrapping
---------------------
    Bootstrapping a workspace for release does the same things as the
    standard workspace bootstrapping procedure except that files that
    are needed to build an ACE/TAO distribution are also generated
    (e.g. man pages).  Dependency tracking is enabled by default since
    Makefile dependencies should be included in ACE/TAO distributions.
