Instructions for installing the dgd-rgx package: This version has been tested with version 1.0.9 of DGD. 1. Copy the files `rgx.c' and `rgx.h' from the ./src directory in this distribution into the src directory of the DGD distribution. 2. Create a directory `regex' in the src directory of the DGD distribution, and copy all of the files from ./src/regex into it. 3. Apply the ./src/dgd.diffs file to your DGD source tree by cd'ing above the DGD distribution and running a command like: patch -p < dgd.diffs (Substituting "dgd.diffs" with the actual pathname to the diffs file.) 4. Rebuild DGD.
