XSI used to be a Cross Platform(X) Server Infrastructure. It had since drifted from cross-platformality considerably. It is now just XSI (Linux).
XSI is a C framework I developed to provide facilities like threading, logging, async I/O and more.
Currently, there is no documentation for XSI.
At this time, only Linux builds are supported.
XSI is typically built as a static library.
