+Interim build-snippet.
+
+The AntLibs depend on the common build infrastructure supplied by the 
+antlibs-common project. In subversion these are included via svn:external
+directive. After migration to git there is need to have successor to that
+directive. Until we have that, we could do a 'manual' git-clone.
+
+The original of this snippet is maintained in the antlib-common project.
