Ok, so here my next try:
| The format of the formulas is those of the dependency
| lines in Debian packages with some extras. That means
| a formula consists of names of fields with a possible
| condition for its content in parentheses. These atoms
| can be combined with an exclamation mark '!' (meaning
| not), an pipe symbol '|' (meaning or) and an coma ','
| (meaning and). Additionally parentheses can be used
| to change binding.
|
| The values checked are directly the headers in the
| repspective index file compared alphabetically. That
| means that each part Fieldname (cmp value) of the for-
| mula will be true for exactly those package that have
| in the Package or Sources file a line starting with
| fieldname and a value is alphabetically cmp to value.
|
| Examples:
|
| reprepro -b . listfilter test2 'Section (== admin)'
| will list all packags in distribtuion test2 with an
| Section field
|
| reprepro -b . -T deb listfilter test2 'Source (==
| blub) | ( !Source , Package (== blub) )' will find all
| .deb Packages with either an Source field blub or no
| Source field and a Package field blub. (That means
| all package generated by an source package blub,
| except those also specifying a version number with its
| Source).
Anything still missing?
