108.It Fl p
109Print warnings about potential problems with manual pages
110to the standard error output.
111.It Fl Q

136is printed to stderr, omitted from the index, and the parse continues
137with the next input file.
138.Sh FILES
139.Bl -tag -width Ds
140.It Pa mandoc.db
141A database of manpages relative to the directory of the file.
142This file is portable across architectures and systems, so long as the
143manpage hierarchy it indexes does not change.
144.It Pa /etc/man.conf

156No errors occurred.
157.It 5
158Invalid command line arguments were specified.
159No input files have been read.
160.It 6
161An operating system error occurred, for example memory exhaustion or an
162error accessing input files.
