While it is possible that the original manifest specified equality or shortucts as full ranges, it is acceptable to display/serialize them as simpler operators.| +Instead of a specific version, the constraint can be specified in terms of the +dependent package's version (that is, its \l{#manifest-package-version +\c{version}} value) using the special \c{$} value. A \c{depends} value that +contains \c{$} is called incomplete. This mechanism is primarily useful when +developing related packages that should track each other's versions exactly or +closely. For example: + +\ +name: sqlite3 +version: 3.18.2 +depends: libsqlite3 == $ +\ + +In comparison operators and ranges the \c{$} value is replaced with the +dependent version ignoring the revision.
