"source evaluates the commands of the specified file in the current 
shell. This is different from starting a new process to perform the 
commands (i.e. fish < FILENAME) since the commands will be evaluated by 
the current shell, which means that changes in shell variables will 
affect the current shell. If additional arguments are specified after 
the file name, they will be inserted into the $argv variable. The $argv 
variable will not include the name of the sourced file.

If no file is specified, or if the file name '-' is used, stdin will be 
read.

The return status of source is the return status of the last job to 
execute. If something goes wrong while opening or reading the file, 
source exits with a non-zero status.

. (a single period) is an alias for the source command. The use of . is 
deprecated in favour of source, and . will be removed in a future 
version of fish."
