plain2html is a utility that converts plain text into HTML code. This is done using the COPL interpreter. Via this webinterface you just put in some plain text in the textfield below and let it be converted into HTML code. You also can do rather complex things: specify a header, footer and/or a macro-definition-file. If you do not want to put in the COPL code in the textfield below, you also can choose a COPL sourcefile to upload.
