Changes made in the v4_5_2 release of ups (2000-06-02):

Added a check in undeclare for the -C switch to inhibit un<chain> actions.
Removed the "unnew" line from the test/scripts/undeclare/log/spot2.in test
log file because undeclare -C is working properly now.

Fixed the problem in which an unsetup would do none of the actions from
an exeActionRequired/Optional reference.  That is, an unsetup with
  Action=unsetup
    exeActionRequired (do_something)
  Action=do_something
    someFunction () ...
would incorrectly not do any someFunction entries.  This was fixed by
copying the p_act_item->unsetup flag to the new_act_item structure
created in the next_cmd routine when handling exeActionRequired/Optional.

Fixed the problem in upsact.c which caused crashes in user-defined
actions with setupRequired/Optional functions including setup options
when a flavor was specified on the command line.  For example, a
user-defined action with the line 'setupRequired (-j <prod>)' would
crash if used with a command line like 'ups user-action -H flavor'.

Added handling of the -e, -j and -v options in unsetupRequired/Optional
functions for previously setup products.  All other options are ignored.
This allows the use of 'unsetupRequired (-j <prod>)' in an unsetup
action with the expected results.  Previously, all options were ignored,
and only the options recorded in the SETUP_<prod> string were used.

Fixed the parsing of the SETUP_<prod> variable during unsetups to
properly handle quoted strings, like the value of the -O options.  This
allows the use of a line like 'exeActionRequired (do_${UPS_OPTIONS})'
in a setup action, without causing errors at unsetup time due to having
an unexpected pair of quotes around the ${UPS_OPTIONS} value.

Dropped the recording of a -v in SETUP_<prod> environment variables.
Unsetups, especially automatic ones, will proceed quietly unless -v is
used on the command line or in unsetupRequired/Optional calls.

Added statistics file logging for dependent products.  The last string
in the record will now indicate whether setupRequired or setupOptional
was used, and what top-level product was responsible:
  "Z" "z1" "NULL" "" "" "user" "2000-05-09 22.19.37 GMT" "setuprequired A a1"
Also fixed the null action string in ups_main.c's statistics logging for
user-defined actions.

Removed the touch of the product directory and archive file, and added
the -f option to the deletion of the archive file in the ups_undeclare.c
file.  Cygwin doesn't allow touching directories, and the touches are
superfluous with the -f, which was already on the product directory
removal.  Cleaned up the clean-up code in the test/scripts/upstst_declare
script to use rm -rf and no touch.

Added status checking and error handling to the code in upsfil.c which
removes the journal and chain files (for undeclares).  Added the
UPS_REMOVE_FILE error message for these checks.

Fixed the 'clean' targets in the doc and man directory Makefiles to not
remove the files necessary for man ups and ups -? to work.  This problem
was introduced in the v4_5 changes to the Makefiles.

Turned on keyword substitution in the handling of ${ARCHIVE_FILE}, as 
an aid in making relocatable ups distributions on CDs, et cetera.

Added the @ form of the COMPILE_FILE keyword to the list -K command.

Removed the a option from and added the chain options (c, d, n, o, t) 
to the modify command.

Added the product name to the verbose "Skipping (un)configure/current ..."
message text in the ups_(un)declare modules.

Added status checking after calls to upsfil_write_file in ups_(un)declare.

Added some spaces after semicolons in shell commands for readability.

Removed the 'ups' alias definition from the ups table file.
