Outputs a limited file tree rooted at the current directory which highlights the position of the argument within the tree. Originally intended for FZF like so:
fzf --preview 'ptf.py {}'

| Leverging FZF for a user interface one can do fuzzy searching with a directory tree and document preview. | |
| The PTF.py creates that tree then colors the path thus giving a graph of the item searched. | |
| Example Usage includes: | |
| - More advance Poorman's Mindmap | |
| - Person/Contact Graph as a filesystem | |
| - Asset Mapping (with pass(1) and LDAP file system structures) | |
| - Maps with stow | |
| - Project Management / Kanboard |
