Project history

xelp predates its GitHub presence by roughly two decades. The original code was written around 2005–2006 as a lightweight debug shell for bare-metal embedded projects. It lived in Subversion for many years, then migrated to Bitbucket (Mercurial, later Git) as those platforms became common in embedded shops.

In 2024 the repository moved to GitHub as a public open-source project. The v0.2.0 tag marks the first GitHub release, not the first version of the library itself.
