First, it +runs persistently, by which I mean that you can tangle as many +files as you like, instead of having to restart the application for +each run. Second, it responds to the 'odoc' Apple Event, so you +can tangle a file from any other application, for instance, your +editor, that will send an appropriate Apple Event. + +Version 1.1 incorporates some important improvements. + +A. An options menu allows control over two features. You can +specify the file extension used for the output file. For instance, +I change this to ``.cp'' when generating C++ files. And you can +instruct Tangle to omit all line and section references. The +line references seriously confuse the Symantec C++ compiler and +debugger. + +B. Tangle has been revised to create temporary files, rather than +replacing the previous versions of its output. Impact then compares the +new versions with the previous ones to see if any changes have been made. +Only if a file has changed is it replaced. This feature frees a +writer to include as many output files as he likes in one web file, +without paying the penalty of unnecessary compilations. + +Messageware. + +Timothy Larkin +PO Box 107 +Brooktondale, NY 14817-0107 +607.539.7299 +tsl1@cornell.edu
