## Project history and usage

miruo is a small network-analysis command-line tool from KLab. Its upstream README describes it in Japanese as a packet-capture TCP session monitor that groups packets by TCP session, summarizes connection and disconnection portions, detects retransmitted segments, long-running communications, reset-aborted sessions, and IP-fragmented segments, and can read files saved by tcpdump -w. Homebrew packages it as a GPL-3.0-only utility with the single miruo executable.

### How it is used

The tool's adoption record is modest but source-backed: FreeBSD added a net/miruo port in 2015 and described it as a network monitor/analyzer that prints packets on the terminal in a neat style and can read tcpdump capture files. Its practical role overlaps with tcpdump and Wireshark workflows, but with a narrower terminal-first focus on making TCP sessions easier to scan rather than offering a full graphical protocol analyzer.
