* deleted the svn:external pkgln and reincluded it in ahdg (NOT
    ahhg!)
  * removed ahhg-symlink-package and added it as a one
    line script (working around subversion 1.1.1's failure
    to handle symlinks correctly)
  * abstracted package symlinking code out of ahhg-build-tools
    into ahhg-symlink-package
  * in scripts updated names of some ADE global variables 
    (ADE_MSG_VERBOSELEVEL)
  * new version of ADE
  * modified ahhg-build-gnu-tools for ahuxley@te30:~/opt/... 
  * added ahhg-build-gnu-tools (builds for hermes not ESO)
  * work in progress.
