dev-libs / c-blosc

Blocking, shuffling and lossless compression library

Official package sites : http://www.blosc.org/ ·

Blosc is a compression library designed to transmit data to the processor cache faster than the traditional non-compressed memory fetch. Compression ratios are not very high, but the decompression is very fast. Blosc is meant not only to reduce the size of large datasets on-disk or in-memory, but also to accelerate memory-bound computations.

proj/gentoo: Initial commit
This commit represents a new era for Gentoo: Storing the gentoo-x86 tree in Git, as converted from CVS. This commit is the start of the NEW history. Any historical data is intended to be grafted onto this point. Creation process: 1. Take final CVS checkout snapshot 2. Remove ALL ChangeLog* files 3. Transform all Manifests to thin 4. Remove empty Manifests 5. Convert all stale $Header$/$Id$ CVS keywords to non-expanded Git $Id$ 5.1. Do not touch files with -kb/-ko keyword flags. Signed-off-by: Robin H.
