+#!/bin/sh
+#
+# 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
