program is being used. You can also specify additional options that
should be passed to the fetch program with \cb{--fetch-option}.
If the fetch program is not specified, then \cb{bpkg} will try to
discover if one of the above program is available and use that.

separate line optionally followed by space and an option value. Empty
lines and lines starting with \cb{#} are ignored. Option values can
be enclosed in double (\cb{\"}) or single (\cb{'}) quotes to preserve
leading and trailing whitespaces as well as to specify empty values.
If the value itself contains trailing or leading quotes, enclose it
with an extra pair of quotes, for example \cb{'\"x\"'}. Non-leading
and non-trailing quotes are interpreted as being part of the option
value.
The semantics of providing options in a file is equivalent to providing
the same set of options in the same order on the command line at the
point where the \cb{--options-file} option is specified except that
the shell escaping and quoting is not required. You can repeat this
option to specify more than one options file."
