      3 # Tests for the special source .USEBEFORE in dependency declarations,
      4 # which allows to prepend common commands to other targets.
      5 #
      6 # If a target depends on several .USE or .USEBEFORE nodes, the commands get
      7 # appended or prepended in declaration order.  For .USE nodes, this is the
      8 # expected order, for .USEBEFORE nodes the order is somewhat reversed, and for
      9 # .USE or .USEBEFORE nodes that depend on other .USE or .USEBEFORE nodes, it
     10 # gets even more complicated.

     16 # Before make.h 1.280 from 2021-12-28, a .USEBEFORE target was accidentally
     17 # regarded as a candidate for the main target.  On the other hand, a .USE
     18 # target was not.
