I think it represents the topology of this little pipeline
'\ *: ',
'| x: pick w1 == ,ERASE,',
'| l: lookup w4 w3 detail master',
'| spec w2.2 1 read w2 nw',
'| spec 1-* 1 fs : substr f1 of w3
'| spec ,EXEC PRIVWU RELOCATE, 1 w1
',TO, nw',
'w4 nw /.'cnf'.'key'./ n sub
'| o: fanout ',
'| substr w8',
'| u: unique first ',
'| spec ,EXEC MKDIR-P, 1 1-* nw',
'| i: faninany',
'| *.output.1:',
