EFEU is suitable for handling data cubes, which
are especially useful for building data
warehouses. It consists of a building system
including mkmf (a xmkmf like Makefile generator),
esh (a powerful C/C++ interpreter), efeudoc (a
document generator with different output formats
(LaTeX, HTML, roff, etc.)). EFEU has a huge set
of C library core features, including robust
memory allocation tools, functions to concatenate
and copy strings with memory allocation, buffers
for dynamically-growing strings and fields, data
structures with reference counters and garbage
collection, and file tools that allow you to
specify pipes wherever a filename is expected and
support automatic implementation of
(de)compression filters (gzip) depending on
filename extensions. It also includes a high-level
interface to files, strings, and anything else you
can read from or write to.
