 Wang–Müller algorithm in PostGIS
 --------------------------------
 
-This is a work-in-progress implementation following "Line generalization based
-on analysis of shape characteristics" by Wang and Müller, 1998.
-
-Structure
----------
-
-There will be 2 deliverables from this folder:
-
-- `wm.sql`, the implementation.
-- paper `mj-msc-full.pdf`, a MSc thesis, explaining it.
-
-It contains a few supporting files, notably:
-
-- `tests.sql` synthetic unit tests.
-- `test-rivers.sql` tests with real rivers.
-- `Makefile` glues everything together.
-- `layer2img.py` converts a PostGIS layer to an embeddable image.
-- `aggregate-rivers.sql` combines multiple river objects (linestrings or
-  multilinestrings) to a single one.
-- `init.sql` initializes PostGIS database for running the tests.
-- `rivers-*.sql` are national dataset snapshots of rivers (`Makefile`
-  contains code to update them).
-- ... and a few more files necessary to build the paper.
-
-Running
--------
-
-`make help` lists the select commands for humans. As of writing:
-
-```
-# make help
-mj-msc-full.pdf    Thesis for publishing
-test               Unit tests (fast)
-test-rivers        Rivers tests (slow)
-clean              Clean the current working directory
-clean-tables       Remove tables created during unit or rivers tests
-help               Print this help message
-wc                 Character and page count
-refresh-rivers     Refresh rivers-*.sql from Open Street Maps
-```
-
-To execute the algorithm, run:
-
-- `make test` for tests with synthetic data.
-- `make test-rivers` for tests with real rivers. You may adjust the rivers and
-  data source (e.g. use a different country instead of Lithuania) by changing
-  the `Makefile` and the test files. Left as an exercise for the reader.
-
-Building the paper (pdf)
-------------------------
-
-```
-# make -j$(nproc) mj-msc-full.pdf
-```
-
-`mj-msc.tex` results in `mj-msc-full.pdf`, which will be at some point
-published. It needs quite a few dependencies, including a functioning Docker
-environment, postgresql client, geopandas, pygments, osm2pgsql, poppler, and a
-"quite extensive" LaTeX installation. This was tested on Debian 11.
-
-Contributing
-------------
-
-Please reach out to me before contributing. As of writing, this is not ready to
-accept broader contributions, TODO:
-
-- [x] Elimination operator.
-- [x] Exaggeration operator.
-- [ ] Combination operator.
-- [ ] CI (unlikely to happen).
-- [x] Known bug in `wm_self_crossing`: the program crashes with a river in
-  Lithuania.
-
-License
--------
-
-GPL 2.0 or later, same as PostGIS.
