#
# dndCard.sh
#
# Usage: dndCard.sh [-t templateFile] [-b bodyFile] inputFile
#
# Takes some fields from an input file and builds a pdf or image of a card from them.
#
# templateFile indicates the latex template to use. Defaults to template.tex and
# should be provided if such file is not in the working directory
#
# bodyFile indicates a file where the body text is stored, for convenience,
# since this field is usually the longer and should be on one line.
#
# Example input file:
# name#Name of item
# typetext#Type of item
# hint#Hint about the type: a short hint about its effect
# body#Extended description of the item
# flavor#Some free form text for flavor
# icon#Icon file, will default to icon.png
# bgimg#Background file of the image, will default to bg.png
# template#LaTeX template file to use. Will default to template.tex
#
# Dependencies
# A LaTeX distribution which provides the xelatex executable, such as Tex Live
#
# Optional depencencies
# ImageMagick: Uses convert to decorate corners of icon and generate image
# Poppler: Uses pdftoppm to convert pdf to image if ImageMagick is available
if ! type xelatex >/dev/null; then

distribution, such as Tex Live, to use this script."
