7zip cmd goodies

Some simple magic spells to ease file management under windows. Here goes...

• compressing all the dirs in the CWD to respectively named 7z archives somewhere else:
  set DEST=C:\some\where\else\note\the\trailing\slash\
  for /D %%i in (./*) do @7z a -mx=9 %DEST%%%i.7z %%i

UPD: more goodies are posted separately with the label 7z
