L.O.B.S.T.E.R.

As a requirements manager I want to have a report of traceability between
requirements (in codebeamer or TRLC) and tests (in C++ or JSON).

As a requirements manager I want the traceability report to show the list of
requirements (from codebeamer or TRLC) which are covered by tests (in C++ or JSON).

As a requirements manager I want the traceability report to show the list of
requirements (from codebeamer or TRLC) which are not covered by tests (in C++ or JSON).

As a requirements manager I want the traceability report to show the list of
tests (in C++ or JSON) covering requirements in (in codebeamer or TRLC).

As a requirements manager I want the traceability report to show the list of
tests (in C++ or JSON) which are not covering any requirement in (in codebeamer or TRLC).

As a requirements manager I want the traceability report to show the fraction of
the number of requirements (in codebeamer or TRLC) which are covered by tests (in C++ or JSON)
divided by the total number of requirements.
The fraction shall be shown as percentage.

IF the list elements given through the config option "inputs" are files with extension rsl and trlc,
THEN all files given in "inputs" parameter shall be consumed.

IF the [[Input_List_Of_Files]] are files with duplicate definitions.
THEN "duplicate_definition" error must be produced.

IF the [[Input_List_Of_Files]] are with invalid extensions OR neither a file nor a directory,
THEN tool shall raise an error.

IF the element given through the config option "inputs_from_file" is a file,
THEN each line in that file shall be interpreted as a path AND shall be consumed.

IF the [[Inputs_From_File]] has files that contain duplicate definitions,
THEN "duplicate_definition" error must be produced.

IF the [[Inputs_From_File]] has files with invalid extensions OR neither a file nor a directory,
THEN tool shall raise an error.

IF both the config options [[Input_List_Of_Files]] AND [[Inputs_From_File]] are provided,
THEN all files given in [[Input_List_Of_Files]] AND [[Inputs_From_File]] parameter shall be consumed.

IF both the config options [[Input_List_Of_Files]] AND [[Inputs_From_File]] has duplicate definitions,
THEN "duplicate_definition" error must be produced.

OTHERWISE, IF both the config options [[Input_List_Of_Files]] AND [[Inputs_From_File]] are not provided,
THEN no files shall be scanned and consumed.

If a output file is specified as command line argument, then the output must be written into that file.
Otherwise, the output shall be written to 'trlc.lobster'.

If a command line argument is prefixed with '@', then the contents of that file
shall be included as arguments to the argument parser.
