Configure freetds database entries. Each attribute denotes
a section within freetds.conf, and the value (a string) is the config
content for that section. When at least one entry is configured
the global environment variables FREETDSCONF, FREETDS and SYBASE
will be configured to allow the programs that use freetds to find the
library and config.
