Comment (by knarf):

 The attached patch introduces versions for capabilities. These can be
 specified in configuration.ccl as in this example:
 {{{
 PROVIDES LORENE
 {
   VERSION 2014
   SCRIPT src/detect.sh
   LANG bash
   OPTIONS LORENE_DIR LORENE_EXTRA_LIB_DIRS LORENE_EXTRA_LIBS
 LORENE_INSTALL_DIR
 }
 }}}
 and can be used in the same file, as in this example:
 {{{
 REQUIRES LORENE (>=0.0.1)
 }}}
 (The version numbers here only serve as example. They are obviously not
 correlated here.)

 Versions can contain alphanumeric characters, and ".+-:". Non-numeric and
 numeric parts are compared from left to right, lexically and numerically
 respectively. Valid operators for requirements are << <= = >= >>. < and >
 are avoided to make it clear that this is strict less or greater than.
