Perhaps it's time for you to read the documentation and the man page for grep. You might want to install the htdig search engine and index the OpenACS documentation.

If you've installed OpenACS, all the documentation is available for perusing from by visiting /doc.

Several times per week, I use htDig to index the OpenACS doc (the bboards at openacs.org, the bug reports, and the wimpypoints), and you can get search that index by visiting http://theashergroup.com/demos/openacs.

Truly, the best way to learn about OpenACS development and architecture from scratch is to work through the first two problemsets in the online course http://philip.greenspun.com/teaching/old-one-term-web-6916 and then use these bulletin boards and other online resources for additional help.

Some of those resources:

  1. a tcl reference book http://www.arsdigita.com/books/tcl/,
  2. a sql reference book http://www.arsdigita.com/books/sql/,
  3. an AOLserver reference book http://www.aolserver.com/docs/tcldev/tcldev.htm
  4. an OpenACS 3.2.5 book http://www.arsdigita.com/doc/index-3.x.adp
  5. an OpenACS 4 book https://openacs.org/4/
  6. A wonderful overview of the ACS, it's development, and the philosophy behind it can be found in Philip and Alex's Guide to Web Publishing, http://www.arsdigita.com/books/panda/
You will have to take some of these references sources with a grain of salt, in particular the ArsDigita ACS 3 docs. It's really a very good introduction to the system architecture and development patterns, but the doc is for a system that is very similar to, but different from OpenACS 3.2.5

(Note to the webmaster: perhaps it's time for OpenACS to start mirroring the tcl/sql for web nerds books, panda, the problemsets, as well as the aD ACS 3.x books. )
