<p align=center><i>Under Construction!!</i></p>
<h2>In the beginning...</h2>
<p>Dr. David Levine had the initial idea for PACE.
ACE+TAO were part of Boeing DII COE project of 2001.
While reviewing the needs for the project and
realizing that ACE_OS (ACE' own adaptation layer)
was quite large and full of potentially avoidable
dependencies, David across the idea that several
POSIX compliant platforms could be encapsulated
into one standard interface, a POSIX interface.</p>
<p>This would potentially allow ACE_OS to port to
a POSIX API, separated from ACE_OS, which would
then port correctly between the minor POSIX
variant operating systems which ACE supported.</p>
<p>This idea quickly developed into the broader
concept that the POSIX interface library could
actually replace the ACE_OS layer in the feature
laden ACE framework library and has since grown
or will grow to include platforms such as Win32
and VXWorks (which lack true POSIX compliance).</p>
<p>As you can see, this creates a benefit for ACE,
namely, PosixACE (PACE) becomes a formal starting
point to begin reducing the complexity and
interdependence problems that had creeped into
ACE over the past 5 years.</p>
