pst-node – Draw con­nec­tions us­ing pstricks

The pack­age en­ables the user to con­nect in­for­ma­tion, and to place la­bels, with­out know­ing (in ad­vance) the ac­tual po­si­tions of the items to be con­nected, or where the con­nect­ing line should go.
The macros are use­ful for mak­ing graphs and trees, math­e­mat­i­cal di­a­grams, lin­guis­tic syn­tax di­a­grams, and so on.
The pack­age con­tents were pre­vi­ously dis­tributed as a part of the pstricks base dis­tri­bu­tion.
