Borland Kylix is a compiler and integrated development environment (IDE) formerly sold by Borland, but later discontinued. It is a Linux version of the Borland Delphi software development environment and C++Builder, which runs under Microsoft Windows. Continuing Delphi's classical Greek theme, Kylix is the name for an ancient Greek drinking cup. The closest supported equivalent to Kylix is the free Lazarus IDE package, designed to be code-compatible with Delphi.
