 This is the README file for the GAP package "IMG".
 
-This package implements Functionally Recursive and Mealy automata in
-GAP. These objects can be manipulated as group elements, and various
-specific commands allow their manipulation as automorphisms of infinite
-rooted trees. Permutation quotients can also be created and manipulated
-as standard GAP groups or semigroups.
+This package implements Iterated Monodromy groups.

+This release (0.0) is the first containing the basic functionality,

-An optional external module (DLL) provides floating-point functions used
-by the "iterated monodromy groups" part of IMG. Its presence or absence
-does not affect the remainder of IMG. To compile it, first make sure that
-your system has C and JAVA compilers. You will need some external libraries,
-in particular levmar and libdogleg. To install them:
-
-* on Linux, use a package-manager such as 'apt-get', 'rpm' if possible. On
-  debian/ubuntu systems, you will need libsuitesparse-dev.
-* on UNIX systems, install the libraries:
-  The dogleg library may be found at https://github.com/Oblong/libdogleg.git
-  The levmar library may be found at http://www.ics.forth.gr/~lourakis/levmar/levmar-2.6.tar.gz
-
-* on Mac OSX, use 'homebrew' (http://mxcl.github.com/homebrew/), and install the formulas by invoking
-  % brew install https://raw.github.com/laurentbartholdi/homebrew/levenberg-marquardt-lib/Library/Formula/levmar.rb
