+Overview
-=============
-
-These are the direct dependencies for running SPI functions :
-
-
-
-Step 1:
-"postgresql-server-dev-<depends on your postgresql version>"
--- sudo apt-get install libpq-dev postgresql-server-dev-13
-
-Step 2:
-To solve gssapi/gssapi.h, use the following command:
-apt-get install libkrb5-dev
-
-Step 3:
-apt-cache search openssl | grep -- -dev
-apt-get install libssl-dev
-
-Compile:
 ========
-gcc -shared -o <file_name>.so <file_name>.c
 
-CALL FUNCTIONS:
+This folder contains results from an experiment by Joseph Xu
-===============
+to use the Postgres SPI. They are not currently used at all
+by the GNU Taler exchange.
