Lex,
before reading your BookMorph document (but I've taken a look onto it),
I want to thank you first for this nice way to publish a proposal.
I haven't seen such a distribution before at this mailing list. It is an
alternative to editing the Swiki or uploading some html- or
ascii-document there (that doesn't mean, that it is not possible to make
such proposals available over the Swiki).
Some time ago I have published some thoughts about
'Structuring packages to minimize 'bad' dependencies'
available via
http://minnow.cc.gatech.edu/squeak/779
with kind of an ascii drawing :-)(
to visualize dependencies. You are using another and *neater* approach.
A few questions regarding your writing experience:
- Was it your first BookMorph?
- Was it difficult to create this BookMorph?
- How much was the amount of time used for layouting and handling the
BookMorph compared to reasoning about the contents of the text?
- Would you recommend to use it to write something with graphics?
Greetings,
Stephan
