+#+TITLE: Tecgraf libraries (IUP, CD and IM) as Common Lisp ASDF System
 
-This system:
+This system includes a shell script, ~update.sh~ which downloads the
+Tecgraf shared libraries for Windows and Linux and places them in
+subdirectory ~libs/~. See also
+https://www.tecgraf.puc-rio.br/iup/en/download_tips.html
 
- - Pulls the latest IUP, CD and IM libraries from locations described
-   at https://www.tecgraf.puc-rio.br/iup/en/download_tips.html
+ - The shared libraries are then included in this repository.
 
- - Verifies the SHA256 checksum of each archive against previously
-   recorded checksums.
+ - The location of the shared libraries can be referenced from
+   ~(asdf:system-relative-pathname "tecgraf-libs" "libs/")~.
 
- - Unpacks the distribution archives.
-
- - Installs the shared libraries into ~(asdf:system-relative-pathname
-   "tecgraf-libs" "libs/")~.
-

+ - On Linux, ~patchelf~ is used set the shared library rpath to
    ~$ORIGIN~ so that the interdependencies between the Tecgraf shared
-   libraries can be found relative to each other. Install ~patchelf~
-   with, for example, ~sudo apt install patchelf~.
- 
- - Display copy and pastable instructions on how to set paths for a
-   specific system.
-
-*NOTE:* On Linux you will need to install system dependencies that the
-IUP libraries are linked against. e.g. ~sudo apt install
-libgtk-3.0~. On Windows, everything is self contained.
