I realized #guix doesn't have 'at' and it'd be fun/interesting to implement it in #guile. Is there any way to get a copy of the POSIX specification or if I refuse to pay for standards documents am I stuck implementing it by reading man pages?
@efraim there's https://pubs.opengroup.org/onlinepubs/9699919799/ which may have what you need; includes a grammar!
@bavThat's a great resource. Thanks!
