It generalizes the tag concept used within 39grohtml and in the future it is hoped that more markup based devices 40can capitalize on this work. It also clearly defines those tags which are 41honoured by grohtml. Note that not all tags are included here. Some 42of the grohtml specific tags (header specific and jobname, etc.) are 43called directly from within www.tmac. The tags defined here are 44reasonably generic and could be applied to other devices. 45.. 46. 47.do if d DEVTAG-NH .nx 48. 49.nr _C \n(.C 50.cp 0 51. 52.\" -------------------------------------------------------------------- 53.\" DEVTAG <name> 54.\" 55.\" Emit a tag <name> 56.\" 57.de DEVTAG 58. tag devtag:\\$* 59.. 60.\" -------------------------------------------------------------------- 61.\" DEVTAG-NEXT <name> 62.\" 63.\" When the troff state changes, emit tag <name> 64.\" 65.de DEVTAG-NEXT 66. taga devtag:\\$* 67.. 68. 69.\" -------------------------------------------------------------------- 70.\" SH <level> 71.\" NH <level> 72.\" tell device we are starting a numbered heading 73.\" Takes a single parameter <level>. <level> 1 74.\" is the outer most level. 75. 76.de DEVTAG-NH 77.
