Dependency graph
================

The complete Themyscira GSM codec libraries & utilities package as presented
here consists of two principal parts:

Division 1: libgsmefr, libgsmfr2 and libtwamr, the set of C code libraries
intended to be usable by other software;

Division 2: various command line utilities that were developed under the
umbrella of this project and are being released accordingly.

Division 2 components have a compile-time dependency on Division 1 (most of
these Division 2 command line utilities link with the libraries), but not the
other way around: none of the core libraries have any dependency on any other
part of this package, not even on each other.

Previous versions of gsm-codec-lib suite had a dependency on libgsm, the
original GSM 06.10 implementation library from 1990s, and our suite was
originally architectured as extending and building on top of libgsm.  However,
this dependency has now been eliminated, and our new GSM codec libraries and
utilities suite is now completely independent from historical libgsm.

Compiling and installing Themyscira libraries and utilities
===========================================================

The configuration and build process has been fully revamped since previous
versions:

* You now need to run ./configure before running 'make' - however, please note
  that our ./configure script is hand-coded, not Autotools/autohell, hence
  there is no autoreconf nonsense involved.

* When you run ./configure, you get the opportunity to either leave CC=, CFLAGS=
  and the install prefix at their default values, or change them to your own
  preferences.

* There are no more mandatory install-lib and install-utils targets, instead
  you get standard 'make install' that installs everything into whichever
  prefix you chose at configure time.  (The ability to install only Division 1
  components with 'make install-lib' or only Division 2 components with
  'make install-utils' is still available, but it is now an experts-only
  option: if you don't see yourself needing this type of split install, then
  you don't need it.)

The default install prefix is /usr/local, following the general standard for
software packages and configure scripts.  To change this install location, pass
the standard --prefix=/wherever option to ./configure script.  In addition to
--prefix, our configure script accepts --exec-prefix, --bindir, --includedir
and --libdir options, following the common standard.

The default compilation settings are CC=gcc and CFLAGS=-O2; to change them,
pass CC=my-whatever-cc and/or CFLAGS="-fwhatever-flags" to configure.
