I would keep your master script somewhere that they cannot alter it else you will have a multitude of differences as people tweak the code about and a nightmare to debug. Assuming that each one has a separate home directory, could you get your script to use an input file in there?

You haven't given us anything to look at, but I would suggest something like this:-
Code:
#!/bin/ksh
# Any comments you want
# Change history perhaps

# Define standard settings
a=1
b=2
c=3

# Define user settings from user home directory file my_variables
. ~/my_variables

# Define defaults for unset variables
z1="${z1:-Hello}"
z2="${z2:=Here}"

# Define functions

# Main script processing
echo "Running with\n\ta=$a\n\tb=$b\n\tc=$c\n\tmy_var=$my_var\n\tz1=$z1\n\tz2=$z2"

exit

Does that give you a framework to start with?

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a    Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
