## プロジェクトの歴史と使われ方
EPIC5 is the current fifth-generation branch of EPIC, the Enhanced Programmable IRC-II Client. Its own site describes EPIC as an ircII fork more than 30 years old, aimed at old-school IRC users, scripters, and people who want an ircII-like client that can be extended heavily through configuration and scripts.
### プロジェクトの歴史
EPIC grew out of ircII culture, where terminal IRC clients were not just chat programs but programmable environments. The EPIC site presents EPIC4 and EPIC5 as two current generations that are not generally interchangeable, with users choosing the branch their scripts require.
The EPIC news archive records active EPIC5 releases in the 2010s, including EPIC5 1.1.8 and 1.1.10 in April 2014 and EPIC5 2.0 on February 13, 2016. The site later marked 30 years of EPIC with EPIC4 3.0 and EPIC5 3.0 releases.
### 採用の歴史
EPIC5 has the adoption pattern of a long-lived terminal IRC tool: it is distributed as source by the upstream project and appears as binary packages in multiple operating-system package collections. The official getting page notes that most operating-system distributions have EPIC4 and EPIC5 packages available.
### 使われ方
Users run EPIC5 as a terminal IRC client and often customize it through EPIC scripts. The official site links separate material for scripts, scripting, installation, and EPIC5 help, reflecting a workflow built around interactive IRC use plus local automation.
### パッケージ好きにとっての重要性
For package maintainers, EPIC5 is a preservation piece from the ircII lineage: small, source-distributed, terminal-native, scriptable, and still relevant to users maintaining old IRC workflows or EPIC script collections.
### タイムライン
- 1990s: EPIC begins as an ircII fork, according to the project's 30-year history note.
- 2014: EPIC5 1.1.8 and 1.1.10 releases are announced.
- 2016: EPIC5 2.0 is released.
- 2020s: The project marks 30 years with EPIC5 3.0.
### Related projects
- EPIC4 is the other maintained EPIC generation and is documented alongside EPIC5.
- ircII is the original IRC client lineage from which EPIC forked.
