git mem/rec bash aliases

.gitconfig

; These aliases are only useful if you work from a directory containing multiple repos.
; mem stores the current branch or commit checked out per repo to a specified file.
; rec reads a specified file in this format and restores the repos to their respective branches or commits.
; This is useful if you're working on or testing multiple branches together and/or simultaneously.
;
; Example:
; git mem /path/to/file
; [change repo configurations, do work, etc.]
; git rec /path/to/file
; [repos are now back in the configuration they were in when git mem was run]
