# Simple script for compiling/converting documents with pandoc because I can never remember how to use it

# Usage:
#   pandoc-make html *.md

usage() {
   cat <<-EOF
		Usage:
		   $0 [output_type] [pandoc_args for file 1] [pandoc_args for file 1] [input_files]

		Examples:
		   $0 pdf *.md
		   $0 .docx *.md  # leading .'s are automatically removed from the output format

		Note:
		   To put a file in pandoc arguments without having it be compiled to its own document, put a './' at the start of the path to it
		   You can have as many arg/file combinations you want
		   The argument array is cleared between input files
