fpc binary package in Ubuntu Focal i386

 The Free Pascal Compiler is an Object Pascal compiler supporting both Delphi
 and Turbo Pascal 7.0 dialects, as well as Mac Pascal dialects. It provides a
 completely portable RunTime Library (RTL) available on many platforms and
 compatible with Turbo Pascal, along with a platform-independent class-based
 Free Component Library (FCL) adding many Delphi extensions and interfacing
 with many popular open source libraries.
 .
 Extensions have been added to the language, such as function overloading,
 creation and linking of shared libraries, and Delphi language extensions
 including classes, exceptions, ANSI strings, and open arrays.
 .
 This dependency package always depends on the latest available version of
 the metapackage pulling in all the FPC packages provided for this
 architecture. Experienced users may instead prefer to install the particular
 packages they require by hand.
