acmetool - 0.0.62-3+b11 main

acmetool is an easy-to-use command line tool for automatically
acquiring TLS certificates from ACME (Automated Certificate Management
Environment) servers such as Let's Encrypt, designed to flexibly
integrate into your webserver setup to enable automatic verification.
.
acmetool is designed to work like make: you specify what certificates
you want, and acmetool obtains certificates as necessary to satisfy
those requirements. If the requirements are already satisfied,
acmetool doesn't do anything when invoked. Thus, acmetool is
ideally suited for use on a cron job; it will do nothing until
certificates are near expiry, and then obtain new ones.
.
acmetool is designed to minimise the use of state and be transparent
in the state that it does use. All state, including certificates, is
stored in a single directory, by default /var/lib/acme. The schema
for this directory is simple, comprehensible and documented.
