# Command-Line Arguments

Inferno has a dedicated module for processing commandline flags and arguments, arg(2). 

## Source

### args.b:17,22



### args.b:24,37



Note: After the processing of all flags, `argv` is re-set from the value contained within `arg` to remove the elements (if any) utilized by flags and their arguments. 

### args.b:41,51
