Task/issue tracking system with command-line interface

Are the any task tracking systems with command-line interface?

Here is a list of features I'm interested in:

• Simple task template
  Something like plain-text file with property:type pairs, for example:

description:string  
some-property:integer required

• command line interface
  for example:

// Creates task
<task tracker>.exe -create {description: "Foo", some-property: 1}   
// Search for tasks with description field starting from F
<task tracker>.exe -find { description: "F*" } 

• XCopy deployment
  It should not require to install heavy DBMS

• Multiple users support
  So it's not just a to-do list for a single person

Ditz is a simple, light-weight distributed issue tracker designed to work with distributed version control systems like darcs and git.
