source: trunk/base/src/port1.0/portchecksum.tcl @ 1015

Last change on this file since 1015 was 1015, checked in by kevin, 18 years ago

Remove 'register' proc.
Now targets have a handle to the target object directly. Alleviates need for
unique names, and simplifies pre-${target}/post-${target} implementation.
Will allow for future enhancement to options and variants.

  • Property svn:eol-style set to native
