NAME

       tart-custom - Template format for LinuxTaRT

DESCRIPTION

       LinuxTaRT  can  use  a  user  defined  template	file  to  generate  the signature.  The name and location of this file can be specified in
       ~/.tartrc, but defaults to the following location:

       ~/.tart-custom

PARAMETERS

       LinuxTaRT recognizes the following directives in the template and replaces them with the corresponding values:

       %c1 - CustomText1 from .tartrc

       %c2 - CustomText2 from .tartrc

       %tg - tagline
	      Randomly selected from the tagline database.

       %hr - horizontal line

       %dt - todays date
	      In the format: Monday, February 25, 2002

       %12 - current hour

	      24-hour format

       %mn - current minutes

       %ap - AM / PM

       %vi - LinuxTaRT version string

       %% - the percent symbol (%)

       Any other characters in the template are copied to the signature as is.

       LinuxTaRT - The Automatic Random Tagline
       %hr
       /dev/random says:
       %tg

       http://mycompany.com
