NAME
  yarac - compile rules to yara
SYNOPSIS
  yarac [OPTION]... [RULE_FILE]... OUTPUT_FILE
DESCRIPTION
  To invoke YARA you will need two things: a file with the rules you want to
  use (either in source code or compiled form) and the target to be scanned.
  The target can be a file, a folder, or a process.

  Rule files can be passed directly in source code form, or can be previously
  compiled with the yarac tool. You may prefer to use your rules in compiled
  form if you are going to invoke YARA multiple times with the same rules.
  This way you’ll save time, because for YARA is faster to load compiled rules
  than compiling the same rules over and over again.

  The rules will be applied to the target specified as the last argument to YARA,
  if it’s a path to a directory all the files contained in it will be scanned.
OPTIONS
  -d <identifier>=<value>   define external variable.
  -w                        disable warnings.
  -v                        show version information.
EXAMPLE
  The -d is used to define external variables. For example: 

  -d flag=true

  -d beast=666

  -d name="James Bond"
