[Info] Portable Object Compiler

The Portable Object Compiler is an Objective-C compatible,
3-pass compiler, for use with C and C++ compilers.


Adopts an evolutionary approach to OOP : adds Smalltalk-like class
libraries and message-sending constructs to the C base language, and
can be used in existing C and C++ projects, without rewriting or
modifying existing code.


The compiler driver, "objc", translates Objective-C objects into plain
C (or Objective-C++ into C++), using a small and portable "all C"
runtime.


Compatible with standard C debuggers and a variety of C development
tools, such as lex, yacc, dbx, gdb, adb, gprof etc. Compatible with
many C compilers, including gcc, SUN acc, HP cc, SGI cc, AIX cc, DEC
cc, WATCOM wcc.


Includes source, HTML documentation and man pages for a standard set
of objects. The compiler's written in Objective-C itself, as a test
for the object libraries.


Provides (since release 1.4.4) automatic passivation and activation of
objects to text files. Includes objects for big-integer arithmetic
and computer algebra.
