# yaml2pdf - turns stuff in Yet Another Markup Language

# into PDF documents.  Very crude - it assumes a

# doc template and stylesheet (hard coded for now)

# and basically cranks out paragraphs in each style

"""yaml2pdf.py - converts Yet Another Markup Language

to reasonable PDF documents.  This is ReportLab's

basic documentation tool.

Usage:

.  "yaml2pdf.py filename.ext" will create "filename.pdf"
