+
+The \c{bpkg} package version constraint may follow the package name in certain
+contexts, such as the manifest values and \c{bpkg} command line, to restrict
+the allowed package version set. It can be specified using comparison
+operators, shortcut (to range) operators, or ranges and has the following
+form:
+
+\
+<version-constraint> := <comparison> | <shortcut> | <range>
+<comparison> := ('==' | '>' | '<' | '>=' | '<=') <version>
+<shortcut> := ('^' | '~') <version>
+<range> := ('(' | '[') <version> <version> (')' | ']')
+\
+
+The shortcut operators can only be used with \l{b#module-version standard
+versions} (a semantic version without the pre-release part is a standard
+version). They are equivalent to the following ranges. \N{The \c{X.Y.Z-} version
+signifies the earliest pre-release in the \c{X.Y.Z} series; see

+^0.Y.Z [0.Y.Z 0.Y+1.0-) if X == 0

+version while the caret (\c{^}) constraint \- also to any further minor
+version.
+
+\N|Zero major version component is customarily used during early development
+where the minor version effectively becomes major. As a result, the tilde
