Eiffel RE2 Files

This small Eiffel library is a wrapper for Google's RE2 regular expression evaluator. The library is void safe. To use the library, 

1. download and install RE2, following the instructions found at http://code.google.com/p/re2/wiki/Install;
2. in a command window, set the environment variables 'RE2' and 'RE2LIB' to the locations of the "re2.h" and other include files, and the libre2.so library respectively;
3. in the same command window, set the ISE_EIFFEL, ISE_PLATFORM, and PATH environment variables required by EiffelStudio. For example, using the default locations:

export ISE_EIFFEL=/usr/local/Eiffel67
export ISE_PLATFORM=linux-x86
export PATH=$PATH:$ISE_EIFFEL/studio/spec/$ISE_PLATFORM/bin
export RE2=/usr/local/include/re2
export RE2LIB=/usr/local/lib

4. launch "estudio" from the command window.
5. include "re2_safe" as a library in the Project Settings.
