pub const MAN_LONG: &str = "Render the manual, from the same clap definitions `--help` prints, so the manual cannot describe a flag the program does not have.
`devp man` at a terminal prints the contents page: every command grouped by what it is for, one line each, plus the flags that go before the command and the exit codes. `devp man <command>` prints that one command's page — the same text `devp <command> --help` prints, because they are the same definition.
The roff source is something `man` formats, not something a person reads, and on Windows there is no `man` to hand it to, so it appears only where something can use it: redirect or pipe the output and it is roff again, so `devp man > devp.1` and `devp man | man -l -` are unchanged. `--roff` forces roff at a terminal too.
`--dir` writes the full set (`devp.1`, `dev-prune.1`, and one `devp-<command>.1` per subcommand) into a directory, ready to copy onto `manpath`.";
