Last change on this file since 166 was 166, checked in by mitsubishi-htm, 13 years ago

Initial integration of VSP into HTM 4.0.1. The version used for JCT3V-B0102 at Shanghai meeting.

VC9 project/solution files updated. Other Visual C++ project/solution files are not updated.
Linux make file updated.

TODO

A second release is expected to include some bug fix and improvements on the interface, e.g. to move switches from macro definition to the configuration file.
A third release is expected after being integrated within HTM 5.x, which is to be used for CE1.h anchor.

Property svn:eol-style set to native
