Annotation of pkgsrc/textproc/zet/DESCR, Revision 1.1
1.1 ! pin 1: This is a command-line utility for doing set operations on files considered as
! 2: sets of lines. For instance, `zet union x y z` outputs the lines that occur in
! 3: any of `x`, `y`, or `z`.
! 4: Two notes:
! 5: -Each output line occurs only once, because we're treating the files as sets
! 6: and the lines as their elements.
! 7: -We do take the file structure into account in one respect: the lines are
! 8: output in the same order as they are encountered. So `zet union x` prints
! 9: out the lines of `x`, in order, with duplicates removed.
