codedoc – LaTeX code and documentation in LaTeX-format file

The CodeDoc class is an al­ter­na­tive to DocStrip (and oth­ers) to pro­duce LaTeX code along with its doc­u­men­ta­tion with­out de­part­ing from LaTeX's or­di­nary syn­tax.
The doc­u­men­ta­tion is pre­pared like any other LaTeX doc­u­ment and the code to be com­mented ver­ba­tim is sim­ply de­lim­ited by an en­vi­ron­ment. When an op­tion is turned on in the class op­tions, this code is writ­ten to the de­sired file(s).
The class also in­cludes fully cus­tomiz­able ver­ba­tim en­vi­ron­ments which pro­vide the au­thor with sep­a­rate com­mands to type­set the ma­te­rial and/or to ex­e­cute it.
