package workstack

// Workstack or ws for short is a program that manages To-Do's in a stack-based fashion.  It tries
// to guide your focus to your three most important tasks such that you do not get distracted by
// other tasks.
// Every task added starts as inactive "[ ]" and can be marked as done by changing the status to
// "[x]".
// When the programs exits Tasks are saved to a tasks.gob file, this will truncate (os.Create) the
// existing file.

// TODO's
// - edit functionality
// - import: read multiple lines from stdin and import them as taks
// - parsing text as Tasks, maybe helper program?
// - clocking functionality with a 'task' command
// - testing:
//	- [ ] add
//  - [ ] done
//  - [ ] undone
//  - [ ] del
//  - [ ] pc
//  - [ ] <no arg>
//	- [ ] ls
//	- [ ] list
//	- [ ] tag
//	- [ ] tagd
//	- [ ] tagl
