# ANSI carriage control characters | |
# Some MVS documents use 0/1/+/- as carriage control. This python will | |
# convert them to markdown/text. The standard ANSI characters are: | |
# | |
# - `space` Single space the line and print. | |
# - `0` Double space the line and print. | |
# - `-` Triple space the line and print. | |
# - `+` Do not space the line and print. | |
# - `1` New Page | |
# | |
# When complete you can convert to PDF with: | |
# pandoc klingon_manual.txt --pdf-engine=pdflatex -V geometry:top=1in -V geometry:left=1.6in -o Klingon\ Manual.pdf | |
