this will produce the dci program in the src/ directory, or in /path/to/your/installation/bin if y

1. Compilation 

To compile the kDCI++ algorithm for FSC:

	- ./configure --prefix=/path/to/your/installation
	- make
	- make install (optional)

this will produce the dci program in the src/ directory, or in 
/path/to/your/installation/bin if you used the--prefix option during the 
configure step and issued a "make install". 

Before the configure step, you might want to turn the -DVERBOSE flag on in 
the src/Makefile.am, to print out some more interesting info during the 
execution of the program.

2. Usage

This implementation of kDCI conforms to the specification in 
http://fimi.cs.helsinki.fi/

	dci input_file min_count [output_file]

+ input file is the transaction databse, in ascii format, with one
transaction per line, each transaction is composed by an ordered list
of non repeated integers, space separated.

+ min_count is the absolute count of an itemsets to be frequent

+ output_file is an optional parameter. if given, frequent itemsets and 
their supports are printed on such file. 

+ during execution some output is printed on screen. if the VERBOSE macro
is not defined in src/Makefile.am, then only the number of frequent patterns
found at each iteration is printed (starting from lenght 0, which always gives
a 1 in the first line). If VERBOSE is defined, than single iteration candidates
and frequent patterns, as well as exec times are printed.
