"source" comes from the C shell.
The Bourne shell (and the Korn shell
successor) did not have it.
Bash was probably the first to suck in
both.

Hi Mike !
>"source" is not in POSIX and thus is not technically portable.
Not in POSIX? Wow, who removed this? Even old AT&T systems did
understand the "source".
... and just a hint about technically portable:
alias source=.
... and even dash shall understand "source"
