Leonid Borisenko - May 13, 2012, 1:28 p.m.
Two variables are searched for value of additional package metadata:


First found variable with defined value wins.

<PKGTYPE> is a parameter of getter and expected to be a distinct name
of specific package type. For example: 'DEB' or 'RPM'.

Variable can contain multiple [one-line] metadata fields, separated by
literal sequence '\n'. Separator can be redefined through variable flag
'separator'. Getter returns found value with separator replaced with
newline character.

As side-effect, searched variables acquired flags 'type' (equals to
'list') and 'separator'.
