-This directory contains an interface to the LiDIA library, version 1.3.1.
-It is already contained in LiDIA-1.3.1 and LiDIA-1.4a1, and is reproduced
-here only as a sample for the use of CLN.
-
-LiDIA is available from
-          ftp://ftp.informatik.th-darmstadt.de/pub/TI/systems/LiDIA
-(The LiDIA group has also a nice Web page.)
-
-LiDIA has an abstract interface to the underlying long integer implementation.
-Using CLN instead of the default libI, lip or gmp has the following
-advantages:
-
-  - Maximum speed on all CPUs, since CLN is based on the highly
-    optimized gmp-2.0.2.
-
-  - Very large integers profit from CLN's Schönhage-Strassen FFT multiplication
-    (asymptotic bit complexity: O(N log N log log N)).
-
-  - Copying integers is fast: no copying is actually involved, only a
-    reference count is manipulated.
-
-  - Small integers (absolute value < 2^29) are represented immediately,
-    thus no memory allocation/deallocation is involved when dealing with
-    small integers.
-
-CLN does all this automatically.
-
-INSTALLATION
-------------
-
-1. Build CLN.
-
-2. Apply the first patch to LiDIA:
-   $ cd .../LiDIA
-   $ patch -p1 < .../cln/lidia-interface/LiDIA-patch1
-
-3. Configure LiDIA as described in its manual.
-
-4. Apply the second patch to LiDIA:
-   $ cd .../LiDIA
-   $ patch -p1 < .../cln/lidia-interface/LiDIA-patch2
-   You may have to do this by hand, if the patch fails.
-
-5. Make two symbolic links
-   $ ln -s .../cln/lidia-interface/interfaces/integers/cln \
-           .../LiDIA/src/interfaces/integers/cln
-   $ ln -s .../cln/BUILDDIR/src .../LiDIA/src/kernel/integers/cln
-   where .../cln/BUILDDIR is the directory in which you have built
-   cln (i.e. there is a file .../cln/BUILDDIR/src/libcln.a).
-
-6. Modify the definitions of the variables CLN_DIR and CLN_TARGETDIR in
-   the file .../LiDIA/config/CONFIG :
-   CLN_DIR must point to .../cln,
-   CLN_TARGETDIR must point to .../cln/BUILDDIR.
-
-7. Build LiDIA as described in its manual.

-LiDIA has an abstract interface to the underlying long integer implementation.
-Using CLN instead of the default libI, lip or gmp has the following
-advantages:
-
-  - Maximum speed on all CPUs, since CLN is based on the highly
-    optimized gmp-2.0.2.
-
-  - Very large integers profit from CLN's Schönhage-Strassen FFT multiplication
-    (asymptotic bit complexity: O(N log N log log N)).
-
-  - Copying integers is fast: no copying is actually involved, only a
-    reference count is manipulated.
-
-  - Small integers (absolute value < 2^29) are represented immediately,
-    thus no memory allocation/deallocation is involved when dealing with
-    small integers.

-This directory contains a special version of CLN, trimmed down for LiDIA.
-It was prepared from CLN version 1.0, found on ftp://ftp.santafe.edu/pub/gnu/,
-by
-  1. removing many unnecessary files (including many source files, the test
-     suite and the documentation),
-  2. adding the file README.LiDIA
