==== Description: ====
The breadcrumbs project is an e-commerce site where users can post
their ads relative to used items or services (like cleaning house,
baby sitting, etc...).

All is devoted to the creation of a "local" economy, a "breadcrumbs"
economy (that is: an economy of "small" things).


The main characteristics of this site are:

- locality
- trust
- money

Locality
--------

The users are locally bound in a group, which is called an "ant
nest". The users are called "ants". The locality is important because
in this way we eliminate the "bank" costs (like PayPal) and also
the shipping costs (because all items are local).

The bank costs are eliminated because every ant nest has its own
treasurer which collects money on behalf of the ants. The system
incorporates a small bank. Every user has his/her account.

Trust
-----

Every user in an ant nest is linked to another by a web of
trust. Every user can tell the system the degree of confidence that
he/she feels towards another user. The system is able to traverse the
graph of the user and compute a trust which a user should have towards
an unknown ant in his/her ant nest.

Money
-----

Every transaction is made in a virtual currency, called the Tao. The
two main characteristics of this currency are:

1) it is floating. That is, unlike the normal currencys, you can have
   prices expressed not only in "cents" but also in "milli" or in
   "micro" Tao. In this case you can have very small prices, for
   things that do not have a great value.

2) It can be issued by the same users. Every user, when he/she buys
   something, can pay the "invoice" with two types of "tao":
   convertible and unconvertible. The first ones are convertible in
   real currency (Euro, Dollar, etc...), the second are inconvertible
   and are simply IOU, which the seller accepts.

   Every time a user posts an ad in the system, the system asks
   him/her the trust needed between seller and buyer to accept
   "unconvertible" taos, which are a _lot_ cheaper.


SOURCE CODE
-----------

The source code is hosted at this site:

http://repo.or.cz/w/breadcrumbs.git

The source code is completely in English, but the web site,
unfortunately, is still in Italian.
