-USAGE: :program:`llvm-remarkutil` count [*options*] <input file>
-
-Summary
-^^^^^^^
-
-:program:`llvm-remarkutil count` counts `remarks <https://llvm.org/docs/Remarks.html>` based on specified properties. 
-By default the tool counts remarks based on how many occour in a source file or function or total for the generated remark file.
-The tool also supports collecting count based on specific remark arguments. The specified arguments should have an integer value to be able to report a count.
-
-The tool contains utilities to filter the remark count based on remark name, pass name, argument value and remark type.
-OPTIONS
--------
-
-.. option:: --parser=<yaml|bitstream>
-
-  Select the type of input remark parser. Required.
-  * ``yaml``: The tool will parse YAML remarks.
-  * ``bitstream``: The tool will parse bitstream remarks.
-
-.. option:: --count-by<value>
-  Select option to collect remarks by.
-  * ``remark-name``: count how many individual remarks exist.
-  * ``arg``: count remarks based on specified arguments passed by --(r)args. The argument value must be a number.
-
-.. option:: --group-by=<value>
-  group count of remarks by property.
-  * ``source``: Count will be collected per source path. Remarks with no debug location will not be counted. 
-  * ``function``: Count is collected per function.
-  * ``function-with-loc``: Count is collected per function per source. Remarks with no debug location will not be counted. 
-  * ``Total``: Report a count for the provided remark file.
-
-.. option:: --args[=arguments]
-  If `count-by` is set to `arg` this flag can be used to collect from specified remark arguments represented as a comma seperated string.
-  The arguments must have a numeral value to be able to count remarks by
-  
-.. option:: --rargs[=arguments]
-  If `count-by` is set to `arg` this flag can be used to collect from specified remark arguments using regular expression.
-  The arguments must have a numeral value to be able to count remarks by
-
-.. option:: --pass-name[=<string>]
-  Filter count by pass name.
-
-.. option:: --rpass-name[=<string>]
-  Filter count by pass name using regular expressions.
-
-.. option:: --remark-name[=<string>]
-  Filter count by remark name.
-
-.. option:: --rremark-name[=<string>]
-  Filter count by remark name using regular expressions.
-
-.. option:: --filter-arg-by[=<string>]
-  Filter count by argument value.
-
-.. option:: --rfilter-arg-by[=<string>]
-  Filter count by argument value using regular expressions.
-
-.. option:: --remark-type=<value>
-  Filter remarks by type with the following options.
-  * ``unknown``
-  * ``passed``               
-  * ``missed``               
-  * ``analysis``             
-  * ``analysis-fp-commute``
-  * ``analysis-aliasing``    
-  * ``failure``
