manual pages for trivial bash scripts and for binaries without command-line arguments

[Boris Pek <tehnick-8@yandex.ru>]

Hi everyone,

Debian Policy (section 12.1) tell us that each program in /usr/bin should has
a manual page. And there is the related warning in Lintian.

But I am interested what is the best practise in case of trivial bash scripts
(which usually set up necessary environment variables and launch binaries)?

Also there is another question about scripts or programs which do not use
command line arguments. (For example, they do not react to --help or --version
arguments.) These can be GUI programs or simple scripts from question above.
Are manual pages useful for them? What maintainers usually do in such cases?

Best regards,
Boris
