define Package/uacme/Default/description
  lightweight client for the RFC8555 ACMEv2 protocol, written in plain C code
  with minimal dependencies (libcurl and one of GnuTLS, OpenSSL or mbedTLS).
  The ACMEv2 protocol allows a Certificate Authority (https://letsencrypt.org
  is a popular one) and an applicant to automate the process of verification
  and certificate issuance. The protocol also provides facilities for other
  certificate management functions, such as certificate revocation.
