[bug-gawk] Doubt in a string

[Rafael Fontenelle]

Hello,

A doubt came up while translating gawk 4.2.62 to Brazilian Portuguese,
so I was hoping someone could clarify it for me.

>From the file awkgram.y, line 2561, the string:

"source files / command-line arguments must contain complete functions or rules"

My doubt is: Is the slash (/) used as "and/or", like source files
and/or command-line arguments, or is it used as a root directory /
(like the souce files start with '/' or something like that) ?

p.s.: It was introduced in:
https://git.savannah.gnu.org/cgit/gawk.git/commit/awkgram.y?id=663aff4ae012468c54d2e994e839d0e75210ef80

Thanks in advance.

Best regards,
Rafael Fontenelle
