Spec

First shared attribs (either public/grouped) must be defined, to do so:

• Simply select the working diagram(also works for pallets)(not an element, e.g. a blank space in diagram)
• Start the shared public/grouped definition using [includes]
  • Any line after [includes] will be assumed as public attribs(all elements will grab it, at the first line of each)
  • For specifying a group, do it using leading # char, like #blues
    • any line after #blues will be assigned for group blues
    • Hint: # char could be escaped using \#
    • Hint: multiple group names would be defined to have a common line, e.g. #blues,reds
• Select the element(s) wish grab the named(non public) groups, and include the related group using #include=
  • For blues case it goes like #include=blues
  • Hint: a named group could be included more than one times
  • Hint: no need to include public group, it's included at the beginning of all elements automatically
  • Hint: one #include= may include more than one named group using ,. e.g. #include=911,992
