# 2013/02/26: MID: wrote a bash script to convert the text file
#                  that was being generated to a PDF file, because
#                  I could. Also fixed the issue of leading spaces
#                  being dropped from lines as we wnt the PDF file
#                  to look correct, didn't matter when the browser
#                  was displaying just text.
# ----------------------------------------------------------------

# Figure out where our prt directory is knowing we are in xxx/mark/scripts
# Then we know where our prt/prt00e/job and prt/prtooe/stc directories
# are to use for output
# (required as I have hercules installed in different directories
#  between test and play).
