qtree – Draw tree struc­tures

The pack­age of­fers sup­port for draw­ing tree di­a­grams, and is es­pe­cially suit­able for lin­guis­tics use. It al­lows trees to be spec­i­fied in a sim­ple bracket no­ta­tion, au­to­mat­i­cally cal­cu­lates branch sizes, and sup­ports both DVI/PostScript and PDF out­put by use of pic­t2e fa­cil­i­ties.
The pack­age is a de­vel­op­ment of the ex­ist­ing qo­bi­tree pack­age, of­fer­ing a new front end.
