Hello Dan and Jennifer,

Well, not really surprising, Peeroml ressembles nothing you have seen in the
AFOL world.
Peeroml is the same as Peeron inventories but using a computer notation rather
than a human-friendly notation. The benefits are you can compute anything you
want from the database, such as:
* sorting sets by date or number of pieces or number of red bricks...
* test if a MOC is an alternate model
* test if a MOC is a combo of two other MOCs
* given a MOC, compute a list of official sets that provide the needed bricks,
plus the list of extra parts you get
* by default Peeroml is color-sensitive, but that can be easily altered
Peeroml is user-programmable. That means if a query or function you need is not
included, you can program it yourself in a simple language, in typically no more
than 3 lines of code.
Peeroml is available here, source and docs included:
Zipped file: http://perso.wanadoo.fr/alphablock/downloads/Peeroml.zip
Auto-exe file: http://perso.wanadoo.fr/alphablock/downloads/Peeroml.exe
The best way to experience Peeroml is to install OCaml and to paste all code
excerpts in the Peeroml doc.
As soon as the tool will be mature enough i plan to remove it from my site and
make it downloadable only via www.peeron.com as Peeron is where eventual users
expect it to be.

No problem, Peeroml only trusts is own computations, that is the inventory
total. Peeroml does other consistency checks, for example a "bonus pack"
inventory must equal the union of its seperate sets. But if it doesn't i won't
bother you, i will just correct what i need to (unless you prefer to be noticed
for any error).
