#MODULE restore_attach
#
#*******************************************************************
"""

**PURPOSE** --

Restores attachments for crafted (attached) parallels to the PMDB
Data is taken from the standard .attachments file which is assumed
to be in the local directory.

**DEVELOPER** --

Alan Patterson

**MODIFICATION HISTORY** --

Initial implementation 05/07/2001 APP.
Python review changes 05/30/2001 APP.
Make test for each existing record more
explicit (i.e include primary) 08/28/2002 APP.

where weekid is the standard calendar week id (yyddd)
-parsus=suid1,suid2,suid3,.... specifies the
crafted parallel SUs that are to be included
in the re-attachments
-r=oldmain,newmain,... specifies which main SUS are
being replaced by new ones. All attachments
using these mains will be restored. The mains
appear as pairs (old,new,old,new,...). This
arguement should only be used if the alignment
and obset structure of the new mains is the
same as the old.
-f= gives the name of the file
containing the attachment records. The default
is yyddd.attachments in the working directory
where yyddd is the weekid (first arg).
If -parsus is missing the user will be queried to
confirm that ALL attachments should be restored.
