I'm trying to write an org-mode file that is being exported to latex, and then built into a pdf file, of the MPD online manual. I'm now trying to show the 'mpf.conf' file which is mostly with commented out lines starting with a hash (#). But that breaks the org-mode export, so how can I have it displayed and exported to latex please? I've tried putting a comma in front of each separate #, which does work, but gives a very untidy export to latex. I've also tried putting '#+begin_src org' before the block of text and #, and '#+end_src' after it, but when I build the pdf after exporting it to latex I get this error report - --8<---------------cut here---------------start------------->8--- Chapter 9. ! Undefined control sequence. \lstset l.1749 \lstset {language=org,label= ,caption= ,captionpos=b,numbers=none} ? x --8<---------------cut here---------------end--------------->8--- Where it just halts and is unable to proceed without correcting it, which I can't do, so I have to say 'x' to break out of it. So what I'm trying to get is a latex file which includes the .conf file and all of its # in the right place and show as # on their own. But how can I do it please?
