Summary
cstream is a general-purpose stream-handling tool like UNIX dd, usually used in commandline-constructed pipes. Features: - Sane commandline switch syntax. - Exact throughput limiting, on the incoming side. Timing variance in previous reads are counterbalanced in the following reads. - Precise throughput reporting. Either at the end of the transmission or everytime SIGUSR1 is received. Quite useful to ask lengthy operations how much data has been transferred yet, i.e. when writing tapes. Reports are done in bytes/sec and if appropriate in KB/sec or MB/sec, where 1K = 1024. - SIGHUP causes a clean shutdown before EOF on input, timing information is displayed. - Build-in support to write its PID to a file, for painless sending of these signals. - Build-in support for fifos. Example usage is a 'pseudo-device', something that sinks or delivers data at an appropriate rate, but looks like a file, i.e. if you test soundcard software. See the manpage for examples. - Built-in data creation and sink, no more redirection of /dev/null and /dev/zero. These special devices speed varies greatly among operating systems, redirecting from it isn't appropriate benchmarking and a waste of resources anyway. - Accepts 'k', 'm' and 'g' character after number for "kilo, mega, giga" bytes for overall data size limit. - "gcc -Wall" clean source code, serious effort taken to avoid undefined behavior in ANSI C or POSIX, except long long is required. Limiting and reporting works on data amounts > 4 GB.

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.
