Versions of packages alsa-utils suggests: pn dialog <none> -- no debconf information Input file is arecordmidi.1 Any program (person), that produces man pages, should check the output for defects by using (both groff and nroff) [gn]roff -mandoc -t -ww -b -z -K utf8 <man page> The same goes for man pages that are used as an input. For a style guide use mandoc -T lint -.- So any 'generator' should check its products with the above mentioned 'groff', 'mandoc', and additionally with 'nroff ...'. This is just a simple quality control measure. The 'generator' may have to be corrected to get a better man page, the source file may, and any additional file may. Common defects: Input text line longer than 80 bytes. Not removing trailing spaces (in in- and output). The reason for these trailing spaces should be found and eliminated. Not beginning each input sentence on a new line. Lines should thus be shorter. See man-pages(7), item 'semantic newline'. -.- The difference between the formatted output of the original and patched file can be seen with: nroff -mandoc <file1> > <out1> nroff -mandoc <file2> > <out2> diff -u <out1> <out2> and for groff, using "printf '%s\n%s\n' '.kern 0' '.ss 12 0' | groff -mandoc -Z - " instead of 'nroff -mandoc' Add the option '-t', if the file contains a table. Read the output of 'diff -u' with 'less -R' or similar. -.-.

Wrong distance between sentences in the input file. Separate the sentences and subordinate clauses; each begins on a new line. See man-pages(7) ("Conventions for source file layout") and "info groff" ("Input Conventions"). The best procedure is to always start a new sentence on a new line, at least, if you are typing on a computer. Remember coding: Only one command ("sentence") on each (logical) line. E-mail: Easier to quote exactly the relevant lines. Generally: Easier to edit the sentence. Patches: Less unaffected text. Search for two adjacent words is easier, when they belong to the same line, and the same phrase. The amount of space between sentences in the output can then be controlled with the ".ss" request. 36:name. A port is specified by its number; for port 0 of a client, the 78:notated.
