NAME

       opmhash - Hasher for summary keywords in Eclipse files

DESCRIPTION

       opmhash:  invalid  option  -- 'h' The purpose of the opmhash program is to load a deck and
       create a summary, by diffing two such summaries it is simple to determine if two decks are
       similar.   For  each keyword a hash of the normalized content is calculated. The output of
       the program will look like this:

       WATER  : 14106203893673265964

       Total  : 7362809723723482303

       Where the 'random' integer following each keyword is the  hash  of  the  content  of  that
       keyword.  The  hashing  is  insensitive  to  changes  in white-space and comments and file
       location. At the bottom comes a total hash of the  complete  content.  The  hash  of  each
       keyword is insensitive to shuffling of keywords, but the total hash depends on the keyword
       order.

OPTIONS

       -l : Add filename and linenumber information to each keyword.

       -s : Short form - only print the hash of the complete deck.

       -S : Silent form - will not print any deck output.

       It is possible to add multiple deck arguments, they are then scanned repeatedly,  and  the
       decks  are compared. In the case of multiple deck arguments the exit status of the program
       will be zero if all are equal and nonzero in case of differences.
