# and is linked with libcurl dynamically, Debian's invention libcurl-gnutls.so
# becomes a runtime dependency. Build the same crap to satisfy runtime dependencies.
# Examples of such software:
# - OnlyOffice DesktopEditors (and probably R7 Office)
# - SberPro https://www.sberbank.ru/ru/legal/new/sbrfbusiness
# GnuTLS, btw, is also capable of GOST.

%description
curl is a client to get documents/files from servers, using any of the
supported protocols. The command is designed to work without user interaction
or any kind of interactivity.
It offers a busload of useful tricks like proxy support, user authentication,
ftp upload, HTTP post, file transfer resume and more.
This version is compiled with SSL (https) support.
