Common GIT commands for different scenarios?

commands.bash

# clone repository to current working directory (cwd)
git clone "{{repo}}" .

# clone a repository to the current directory, "symlinking" git files elsewhere, checking out single file
git clone -n --separate-git-dir="{{extpath}}\{{ProjectName}}" "{{path}}\{{ProjectName}}" .
git checkout HEAD {{file}}
## Explanation:
## 1.	git
##	clone
##	-n		no files checked out, just history; could use `--bare` as well?
##	--separate-git-dir={{extpath}}	where to put the `.git` directory, not cwd
##	{{path}}	the repository to clone
##	.		use current working directory -- won't work if not empty
## 2.	git
##	checkout
##	HEAD		latest
##	{{file}}	the filename
