Split Node-specific stuff from BuildInfo into a separate NodeInfo class. Add size info to the File information we collect.

 cached content signature used.
 A negative value means to never cache the content
 signature and to ignore the cached value if there already is one. A value
-of 0 means to always cache the signature, no matter how old the file is.
+of 0 means to always use the cached signature,
+no matter how old the file is.
 
 .TP
 -n, --just-print, --dry-run, --recon
 
   - Print various --debug= stats even if we exit early (e.g. using -h).
 
+  - Really only use the cached content signature value if the file
+    is older than --max-drift, not just if --max-drift is set.
+
+  - Remove support for conversion from old (pre 0.96) .sconsign formats.

   From Wayne Lee:
 
   - Avoid "maximum recursion limit" errors when removing $(-$) pairs
               Python function Actions (including various pre-supplied
               SCons Actions) be rebuilt.
 
+          --  REMOVED CONVERSION FROM PRE-0.96 .sconsign FORMATS
+
+              Because this release involves so many other signature
+              changes that cause rebuilds, the support for automatically
+              converting signature information from .sconsign files
+              written by SCons versions prior to 0.96 has been removed.
