@item -i
@itemx --info
@opindex @option{-i}
@opindex @option{--info}
By adding this flag you will get a metadata for a pony printed, rather than the pony
itself. The output will beformated with bold tag names. The output will be wrapped
according to the @option{-W} option.
@item +i
@itemx ++info
@opindex @option{+i}
@opindex @option{++info}
This works just like the @option{-i} option, except the pony will use the output
has her message rather that just print that information.
@item -r RESTRICTION
@itemx --restrict RESTRICTION
@opindex @option{-r}
@opindex @option{--restrict}
This option is used to restrict which ponies can be randomly select based one their
metadata. The restrict is given is disjunctive normal form, and can hence express any
logical combination, however only for tags with one entry. For tags with multiple
values all values are tested and of one of them passes a test passes.
The argument for @option{--restrict} is a @code{+} separated list of values that all
must be satisfied for a pony to be qualified for random selection. The option
@option{--restrict} can be used multiply times, only one of them need to be satisfied
for a pony to qualified for random selection.
A value in the argument is a combination of the tag name and tag value on the form
@code{NAME=VALUE}. Additionally if the tag names ends with a question mark (@code{?})
the tag is satsified if the tag is missing; if the value starts with a bang (@code{!})
the test is inverted. Using just a bang means that the test passes for and only for
all ponies with the tag definied; using the question mark and a empty value means
that the test passes for all ponies; finally, using the question mark and just a bang
for the value means that the test passes for and only for all ponies without the tag
definied.
For most shells, if not all, trick to not need to use disjunctive normal form is to
use @code{@{ @}}. For example if you use
@option{--restrict=@{eye=@{blue,green,cyan@}+coat=@{black,grey@},coat=white@}}
(note that there is no whitespaces) means that only ponies with white coat will be
randomly selected as will as ponies with black or grey coat provided that they
have either blue, green or cyan eyes.
