+  * housekeeping, internal program adjustments (i.e. unrelated to output)
+    * lib, moved lib base to v0 branch (major version preceded by a v), [from
+      major.minor version (this version would otherwise be 0.53)], primarily to
+      simplify reading of scm history (with fewer lib directory changes)
+    * issues with strings and arrays (flatten and compact some arrays)
+    * changed require from Constant + '/path' back to "#{Constant}/path"
+    * various little things
+    * cleanup, including cleaning of end of line (hanging white) spaces
+
+  * Note: dcc, several hash values change.
+
+  * moved to git for scm including git-buildpackage 
+   (from a combination of mercurial and dars + darcs-buildpackage, [don't ask,

The resulting zipped file has a .zip suffix added to the markup source file name by default, though a .ssp suffix is also recognised. The directory structure of the unzipped file is understood by sisu, and sisu commands can be run  within it. SiSU commands can be run against a sisupod contained in a local directory, or provided as a url on a remote site. As there is a security issue with skins provided by other users, they are not applied unless the flag --trust  or --trusted  is  added  to  the  command  instruction,  it  is recommended that file that are not your own are treated as untrusted. This provides a convenient way of packing documents files for sending Note: if you wish to send multiple files, it quickly becomes more space efficient to tar and gzip the sisu markup directory, (without the _sisu_processing subdirectory) rather than the individual files for sending).
