N:
N:    This man page provokes warnings or errors from man.
N:
N:    "cannot adjust" or "can't break" are trouble with paragraph filling,
N:    usually related to long lines. Adjustment can be helped by left
N:    justifying, breaks can be helped with hyphenation, see "Manipulating
N:    Filling and Adjusting" and "Manipulating Hyphenation" in the manual.
N:
N:    "can't find numbered character" usually means latin1 etc in the input,
N:    and this warning indicates characters will be missing from the output.
N:    You can change to escapes like \[:a] described on the groff_char man
N:    page.
N:
N:    Other warnings are often formatting typos, like missing quotes 
around a
N:    string argument to .IP. These are likely to result in lost or 
malformed
N:    output. See the groff_man (or groff_mdoc if using mdoc) man page for
N:    information on macros.
N:
N:    This test uses man's --warnings option to enable groff warnings that
N:    catch common mistakes, such as putting . or ' characters at the 
start of
N:    a line when they are intended as literal text rather than groff
N:    commands. This can be fixed either by reformatting the paragraph 
so that
N:    these characters are not at the start of a line, or by adding a
N:    zero-width space (\&) immediately before them.
N:
N:    At worst, warning messages can be disabled with the .warn 
directive, see
N:    "Debugging" in the groff manual.
N:
N:    To test this for yourself you can use the following command:
N:     LANG=en_US.UTF-8 MANWIDTH=80 man --warnings -E UTF-8 -l <file> 
>/dev/null
N:
N:    Severity: normal, Certainty: certain
N:
richard@araminta:~/src/newstools$ LANG=en_US.UTF-8 MANWIDTH=80 man 
--warnings -E UTF-8 -l 
debian/rjk-spoolstats/usr/share/man/man1/spoolstats.1.gz >/dev/null
