/*                                                                      
 *      MODULE NAME: update_sharp_keys.c
 *
 *	DESCRIPTION: This module recalculates SHARP keywords. This is accomplished by 
 *      cloning a record, recalculating keywords of choice (i.e., user input), 
 *      and pointing to the same segments as the old record. Associated error keys
 *      are computed by default. 
 * 
 *      This module accounts for versioning by appending to the keyword CODEVER7 and HISTORY:
 *      CODEVER7 will contain multiple lines: the production build of sharp.c, the 
 *      production build of include file sw_functions.c, and the production build
 *      of update_sharp_keys.c. HISTORY will include a human-readable sentence about which
 *      keywords were updated. 
 * 
 *      N.B.: This module calculates the keyword specified in keylist and then does a 
 *      drms_copykeys() to copy over all the remaining keywords. However, if [1] a keyword
 *      does not exist in the .jsd files of the input series, and [2] said keyword X is not
 *      specified in keylist, then [3] drms_copykeys() will copy DRMS_MISSING_VALUE into 
 *      keyword X for all the output series.
 *
 *      This module does not produce segments.
 *
 *      INPUTS     : -- DRMS SHARP series
 *                   -- DRMS SHARP CEA series
 *                   -- HARPNUM
 *                   -- comma separated list of keywords to recalculate
 *                   -- DEBUG flag (use like this debug=debug)

 *	Version    :   v0.0	Jun 14 2013
 *                     v0.1     Feb 11 2014 Added different input and output series
 *
 *	EXAMPLE    :
 *      update_sharp_keys sharpseriesin=hmi.sharp_720s sharpceaseriesin=hmi.sharp_cea_720s //
 *      HARPNUM=1 sharpseriesout=hmi.sharp_720s sharpceaseriesout=hmi.sharp_cea_720s keylist=USFLUX,TOTPOT debug=debug
