       ecl - Embeddable Common LISP


       ecl [-dir dir] [-load file] [-eval expr]
           [-compile file
               [-o  ofile]  [-c  [cfile]] [-h [hfile]] [-data [datafile]] [-s]


       ECL stands for Embeddable Common-Lisp.  The ECL project is an effort to
       modernize   Giuseppe   Attardi’s   ECL   environment   to   produce  an
       implementation of the Common-Lisp language which complies to  the  ANSI
       X3J13 definition of the language.

       The current ECL implementation features:

       ·      A bytecodes compiler and interpreter.

       ·      A translator to C.

       ·      An interface to foreign functions.

       ·      A dynamic loader.

       ·      The possibility to build standalone executables.

       ·      The Common-Lisp Object System (CLOS).

       ·      Conditions and restarts for handling errors.

       ·      Sockets as ordinary streams.

       ·      The Gnu Multiprecision library for fast bignum operations.

       ·      A simple conservative mark & sweep garbage collector.

       ·      The Boehm-Weiser garbage collector.

       ecl without any argument gives you the interactive lisp.


       -shell file
                 Executes  the given file and exits, without providing a read-
                 eval-print loop.  If you want to  use  lisp  as  a  scripting
                 language,  you  can  write #!${exec_prefix}/bin/ecl -shell on
                 the first line of the file to be executed, and then ECL  will
                 be automatically invoked.

       -norc     Do not try to load the file ~/.eclrc at startup.

       -dir      Use dir as system directory.

       -load file
                 Loads file before entering the read-eval-print loop.

       -eval expr
                 Evaluates expr before entering the read-eval-print loop.

       -compile file
                 Translates  file  to  C  and  invokes the local C compiler to
                 produce a shared library with .fas as extension per  default.

       -o ofile  When  compiling file name the resulting shared library ofile.

       -c cfile  When compiling name the intermediary C file cfile and do  not
                 delete it afterwards.

       -h hfile  When  compiling  name  the intermediary C header hfile and do
                 not delete it afterwards.

       -data [datafile]
                 Dumps compiler data into datafile or, if not supplied, into a
                 file   named  after  the  source  file,  but  with  .data  as

       -s        Produce a linkable object file.  It  cannot  be  loaded  with
                 load,  but  it  can  be used to build libraries or standalone
                 executable programs.

       -q        Produce less notes when compiling.

       The options -load, -shell, and -eval may appear any  number  of  times,
       and they are combined and processed from left to right.


       The  original  version  was developed by Giuseppe Attardi starting from
       the Kyoto Common  Lisp  implementation  by  Taiichi  Yuasa  and  Masami
       Hagiya.   The current maintainer of ECL is Juan Jose Garcia Ripoll, who
       can be reached at the ECL mailing list.


       ~/.ecl, ~/.eclrc
              Default initialization files loaded at startup unless the option
              -norc is provided.  (if they exist).
