# web.sed -- quick type html with simplified syntax # for headings, paragraphs, etc.. # To get css, have an "index.css" in same directory, or edit this file. # sed operates on one line of the source file at a time, and the # changes are almost all cumulative. After the making of tags below, # paragraphs are lines to sed, which affects the order in which # certain substitution commands can be given. # An awk routine replaces the @enumber and @tnumber with respective # numbers starting with "1". It may be separate script or # placed in the bash script or batch file that you use. # The last backslash at \ is necessary to get space before # title. # Insert boilerplate before first line. Not cumulative. # This apparently has to be the first thing in file.
