Another method of specifying config information in shell scripts that
I like to use, is to use bash's parsing itself.

For example, using bash syntax:

---------- script.conf -----------

#
# This is a sample config file
#

# Directory where output goes
OUTPUTDIR="/home/cdfrey/output"

# Today's date in preferred format
TODAY=$(date +%Y%m%d)

---------------------------------

Then just source the config file in your script:

----------- script.sh --------------
#!/bin/sh

. /etc/script.conf

echo "Today is: $TODAY"

[...]
------------------------------------
