Made a start on making this shellscript more portable:  Now using `$HOME' instead of `/home/lfinsto'.
!! TODO:  The directory `$HOME/irods_proj/irods_master/Finston/gwrdifpk/src/.libs' is still "hard-wired".
I plan to add a command-line argument to fix this.
Merged in changes from development repository:

Changed the rules
`statement: DELETE_YY HANDLE_VALUE_YY STRING_YY delete_handle_option_list',

`statement: DELETE_YY HANDLE_VALUES_YY STRING_YY delete_handle_option_list',

`statement: DELETE_YY HANDLE_VALUE_YY HANDLE_VALUE_SPECIFICATION_YY delete_handle_option_list'

and

`statement: DELETE_YY HANDLE_VALUES_YY HANDLE_VALUE_SPECIFICATION_YY
delete_handle_option_list'

to

`statement: DELETE_YY HANDLE_VALUE_YY delete_handle_option_list STRING_YY',

`statement: DELETE_YY HANDLE_VALUES_YY delete_handle_option_list STRING_YY',

`statement: DELETE_YY HANDLE_VALUE_YY delete_handle_option_list HANDLE_VALUE_SPECIFICATION_YY'

and

`statement: DELETE_YY HANDLE_VALUES_YY delete_handle_option_list HANDLE_VALUE_SPECIFICATION_YY',

respectively.

That is, now putting options before the non-option handle value argument.

Changed rule
`statement: DELETE_YY HANDLE_YY STRING_YY delete_handle_option_list'
to
`statement: DELETE_YY HANDLE_YY delete_handle_option_list STRING_YY'.
That is, now putting options before the non-option handle argument.
Now allowing `--' and `+' as prefixes to `immediate' and `IMMEDIATE'.
Edited.
