afs opened a new issue, #2862:
URL: https://github.com/apache/jena/issues/2862

   ### Version
   
   5.2.0
   
   ### Feature
   
   Sometimes it is convenient to manage the arguments for a command line 
invocation.
   
   Use cases:
   
   * There may be many arguments and a single command line becomes cluttered.
   * The arguments for the command may be the responsibility of a different 
group to the running of the script making the invocation.
   * Enable verbose output for development.
   * The arguments file can be managed separately from the script or process 
that runs the command, especially as some commands may take sensitive values as 
arguments (e.g passwords) and environment variables are not always convenient.
   * As a record of the arguments that may change over time.
   
   
   Syntax: `@filename` as the only argument to the command.
   
   File syntax:
   ```
   # Example arguments file
   # One line per argument or argument value.
   # There is no escape mechanism.
          ## Another comment
   --arg1
   ## Split at first space after the argument name
   --arg2 value
   ## Ignore leading and trailing horizontal white space 
        --arg3=value
   # Use --arg= for an empty string value
   --empty=
   -q
   ```
