+========================
+
+Purpose
+-------
+The repository contains software from the software subdirectory at
+http://www.software-for-seismometry.de/.
+Erhard Wielandt gave his consent to make his code available through gitlab for
+anonymous download (see [COPYING](COPYING)).
+The contents of the repository will be updated from time to time by vendor
+updates.
+Please check the original location (http://www.software-for-seismometry.de/)
+for the most recent versions and accompanying material.

+
+**Welcome to Erhard Wielandt's website for free seismological software**
+
+This website offers free software for practical use, especially for the
+design, calibration, and testing of seismographs. It also contains educational
+software and other material used in courses and workshops on seismometry.
+Problems of seismometry and theoretical seismology are treated in the 
+'misc.texts'.
+
+If you are interested in software, please start from the 
+[software overview](software-overview.doc).

+
+Contents
+--------
+The git repository will contain only source code, examples of configuration
+files, and text files containing program documentation.
+All binary executables, binary libraries or tar-balls present at the source
+location will not be included in the git repository.
+Example data will be made available on a separate branch
+`vendor-with-examples`.
+
+Contents of the current vendor snapshot are presented in
+ * [CONTENTS-tree.txt](CONTENTS-tree.txt)
+ * [CONTENTS-ls-lR.txt](CONTENTS-ls-lR.txt)
+
+Layout
+------
+Source code is provided on branch `vendor`.
+
+### branches
+`vendor-preview`:        preview complete contents of
+                         http://www.software-for-seismometry.de/
+                         just before next vendor snapshot  
+`vendor`:                vendor import branch (just code, no example data)   
+`vendor-with-examples`:  vendor import with data file examples              
+`master`:                will point to `vendor`                              
+`workbench`:             separate branch providing tools for vendor imports   
+
+### merge hierarchy
+Branch `vendor-with-examples` never shall be merged into `vendor` such that
+users can easily discard the example data files from their clone, if they want
+to.
+The branch `workbench` does not contain files from
+http://www.software-for-seismometry.de/
+and will always be kept separate (no merges).
