DESCRIPTION


replacekey is aimed at replacing keywords in a FITS file's header by new keywords provided

ALGORITHM


The user can provide a new_keyword, an old_keyword, a value and a comment. replacekey
first searchs for old_keyword if provided. If it finds it, it replaces the associated card
by the new one (new_keyword=value/comment). If old_keyword is either not found or not

key" in myfile.fits: % replacekey -k "NEW" -v "3.14" -c "This is a usefull key" -K "OLD"
