/*
* Defines a resolvable (something other packages can depend upon).
* Each resolvable is defined as a name (with an optional type prefix),
* an optional version, and an optional compatibility version (the least
* version the resolvable is backwards compatible with).
*
* resolvable ::= <name>['='<version>]['compat' '>=' <version>]
* name ::= [<type>':']<word>
* type ::= 'lib' | 'cmd' | 'app' | 'add_on'
*
* The type doesn't have any specific meaning to the dependency resolver,
* it just facilitates doing specific queries on the repository (like "is
* there any package providing the 'svn' command that the user just typed?").
* At a later stage, more types may be added in order to declare additional
* entities, e.g. translators.
*
* String examples:
* haiku=r1
* lib:libssl=0.9.8i
* subversion=1.5 compat>=1.0
* cmd:svn
