# ------------------------------------------------------------- 
#  udbToAny.ksh 
# 
#     This script was leveraged from "databaseConversionTool.ksh" 
# it should provide a superset of the functionality of that script; 
# however the primary motivation was to get away from the use of
# multiple divergent parsers for the ".udb" style database.  The
# parser has been moved into an awk "library" file: udbParseLib.awk.
# this parser can and should be used by all scripts wishing to parse
# the ".udb" data bases. 
#
# ----------------------------
# new features:
#
#  -toDB		to convert to old mksubmit-style ".db" format
#  -toLst  		to convert to old domain-port-style ".lst" files
#  -toCustom <prt>	to specify a print routine for a custom format
#  -custom <awklib>	to specify a library containing custom print routines.
#  -udbParseLib <awkLib> to specify a library containing an alternate parser. 
#  -mailTo  <user>	to specify an administrator who will receive mail
#			concerning parsing errors. 
#
#  -Database		is now obsolete (although it will still work)
#  <udbfile> ... ...	The script can now take multiple udb files (Only the
#			defaults specified in the first udb file will apply).
#  
# ----------------------------
#
#     This script converts a universal database to an 
# HP OSF style System Definition Database (SDD) file,
# or a set of args suitable to supply to the Chelmsford deliver
# tool, or a set of commands to build a delivery tree.
# For more details, please refer to the "X11 and VUE for HP_OSF/1.0"
# document.
#
#  This script was leveraged (read hacked extensively) from
#  the "udbToDb" script by Jim Andreas.  Ron Voll authored the
#  original "udbToDb" script.
#
# -------------------------------------------------------------

# usage:  databaseToSDD.ksh Option udbFile
#
# where Option is one of the following:
#
# -toDB		     convert a .udb to ".db" format
# -toLst	     convert a .udb to ".lst" format
# -toSDD             convert a .udb to SDD format
# -toDeliverArgs     convert a .udb to args that the deliver tool likes
# -toReleaseTree     convert a .udb to a script to build a delivery tree
# -toCheckBuild      convert a .udb to a script to check the items in a build
# -toFileList        convert a .udb to a list of files for carbon units
# -Machine           specifies 3,7,8 for hp-ux releases
# -ReleaseStream     {hp-ux, osf, whatever} 
# -NoDefaults        do not convert any records labeled default
# -toTargetList      convert a .udb to a list of target files in product tree
#                      the leading path is stripped and just the target
#                      file is left - for easy diffing with some other
#                      version of a release
# -custom <awkFile>		Supply a custom "awk" print library
# -toCustom <prt routine>
# -udbParseLib <awkFile>	Supply an alternate  "awk" parser library


# -------------------------------------------------------------
#  ConvertRoutine
# 
#   This ksh function invokes awk to do all of the dirty
# work.  The DoAction variable is consulted only in the
# final stages of printing the desired info after the
# .udb "phrases" are parsed.
