#Parse the input text file and add cards to a cardpage document.
#Input text file has two types of line:
#
#Variable setting:
#
#   edition = <text>
#   author = <text>
#   type = <text>
#   background = <filename>
#   panel = <filename>
#   back = <filename>
#
#Card definition:
#
#   <text> * <text>
#
#(the first text field is the card value, the text after the '*', if present,
# is the card comment).
#
#After an edition, author, or type field is set, it is used for all card
#definitions parsed until another line changes its value. All blank lines are
#ignored, as are lines starting with a # character.
#
#No check is made for field lengths, so keep them reasonable, or the cards 
#will get garbled.
#
# Andrew Williams
