SYNOPSIS

       taskl // * < 

       taskl (-v | --version)

       taskl (-h | --help)

DESCRIPTION

       Task/L  compiles  a  system configuration, described in YAML, to a Bash

       script which can be used to instantiate the configuartion.

       The YAML files describes tasks which have a body  and  dependencies  on

       other  tasks. Tasks can accept arguments, which are templated in to the

       commands that make up the body and can be passed on  to  the  dependen-

       cies.

       The  body of a Task/L task is a list commands, where each command is an

       array of strings (without any of the usual shell  escaping  headaches).

       If the headword of the command is an HTTP or HTTPS URL, then the target

       of the URL will be downloaded, marked executable and run with the given

       arguments at run time.

DEPENDENCIES

       Scripts generated by taskl rely on bash and curl.

APPLICATION

       taskl //nginx < example/servers.yaml | ssh [email protected] sudo bash

       The  generated scripts can be given arguments to run specific task bod-

       ies (for debugging), to show the plan and to  show  the  subtasks  that

       were compiled in.

       taskl //nginx < example/servers.yaml > nginx.bash

       chmod ug+x nginx.bash

       # Show help for installer script.

       ./nginx.bash -h
