Format of a deck file:

it’s a sequence of cards. each card has two or more sides called x, y and z in the examples.

possible syntaxes:

• oneliner:

    : x / y / z

• multiline:

    * x
      x
    / y
      y
    / z
      z

• multi-oneliner:

    = x
      y
      z

• binary: (two sides only, the first is a oneliner)

    @ x
      y
      y

• any empty / white lines at the beginning or end of a side will be trimmed

• the whitespace at the start of each line is conserved, and any syntax character {=,:,/,*} recognized as such is replaced by a space to keep alignment
