Metacat

new README for 1.0.2

More changes to build process. No longer need the instdtd target
because it is handled by the install target. Updated installation
instructions accordingly.

Improvements to the build process that make it easier to install the DTDs
form EML. There are now three new targets in the build.xml file:

getdtd: uses cvs to get a working copy of a tagged release of eml
  instdtd: copies the DTDs from the build directory to the install directory...
