The PerlDoc file is the full text file, the TOC file is its table of
contents.  These files are also available in html, pod, and postscript
formats if you go up a directory.

These files contain embedded <CHARACTER>-<BACKSPACE> sequences to indicate
emboldening and underlining.  If your text previewer is too brain-damaged
to handle this, get a new one.  The "less" viewer is preferred.  If you
still can't handle it, then run this to fix it:

     perl -i.bak -pe 's/.\010//g' file

But you still need a better viewer.
