Here we provide only a quick overview. The package provides a single ensemble command, '''struct::list''', which provides the following methods:

    :   '''assign''' ''sequence varname'' ?''varname ...''?
    :   '''dbJoin'''  ?'''-inner'''|'''-left'''|'''-right'''|'''-full'''?   ?'''-keys''' ''varname''?  '''{'''''keycol table'''''}'''...
    :   '''dbJoinKeyed'''  ?'''-inner'''|'''-left'''|'''-right'''|'''-full'''?   ?'''-keys''' ''varname''? ''table...''
    :   '''equal''' ''a b''
    :   '''filter''' ''sequence cmdprefix''
    :   '''filterfor''' ''var sequence expr''
    :   '''firstperm''' ''list''
    :   '''flatten'''  ?'''-full'''?   ?'''--'''?  ''sequence''
    :   '''fold''' ''sequence initialvalue cmdprefix''
    :   '''foreachperm''' ''var list body''
    :   '''iota''' ''n''
    :   '''lcsInvert''' ''lcsData len1 len2''
    :   '''lcsInvert2''' ''lcs1 lcs2 len1 len2''
    :   '''lcsInvertMerge''' ''lcsData len1 len2''
    :   '''lcsInvertMerge2''' ''lcs1 lcs2 len1 len2''
    :   '''longestCommonSubsequence''' ''sequence1 sequence2''  ?''maxOccurs''?
    :   '''longestCommonSubsequence2''' ''sequence1 sequence2''  ?''maxOccurs''?
    :   '''map''' ''sequence cmdprefix''
    :   '''mapfor''' ''var sequence script''
    :   '''nextperm''' ''perm''
    :   '''permutations''' ''list''
    :   '''repeat''' ''size element1'' ?''element2 element3 ...''?
    :   '''repeatn''' ''value size...''
    :   '''reverse''' ''sequence''
    :   '''shift''' ''listvar''
    :   '''split''' ''sequence cmdprefix'' ?''passVar failVar''?
    :   '''swap''' ''listvar i j''

The prefix ''lcs'', as used by a number of the methods above, stands for '''longest common subsequence'''.
