The keyword specifies how option works when specified multiple times:
- single: the last provided value replaces the earlier ones
- append: it supports being provided multiple times
- boolean: on/off values
- mutex: flag-like option that disable anoter flag
The 'gen.pl' script then outputs the proper and unified language for
each option's multi-use behavior in the generated man page.
The multi: header is requires in each .d file and will cause build error
if missing or set to an unknown value.
Closes#9759
gen.pl now generates a warning if the "See Also" field is not filled in for a
command line option
All command line options now provide one or more related options. 167
"See alsos" added!
Closes#8019
Since "too old" versions are no longer included in the generated man
page, this field is now mandatory so that it won't be forgotten and then
not included in the documentation.
Closes#7786
The file format for each option now features a "Example:" header that
can provide one or more examples that get rendered appropriately in the
output. All options MUST have at least one example or gen.pl complains
at build-time.
This fix also does a few other minor format and consistency cleanups.
Closes#7654
