Go to downloads for the latest source (or see Tags above for releases).
Then follow the directions in Build.
Jsi is version-controlled using fossil.
The simplest way to keep updated is by pulling down the Jsi fossil repository:
fossil clone http://jsish.org/jsi jsi.fossil fossil open jsi.fossil cd jsi ./configure make
To get fossil:
- On Ubuntu: "apt-get install fossil", or
- Get it from http://www.fossil-scm.org/index.html/uv/download.html
You can download a binary for Linux or Windows from http://sourceforge.net/projects/jsish/files/.
Binaries are unsupported, but they are the fastest way to give jsish a test drive without having to build anything.
