Description: command line tool for transferring data with URL syntax
 curl is a command line tool for transferring data with URL syntax, supporting
 DICT, FILE, FTP, FTPS, GOPHER, HTTP, HTTPS, IMAP, IMAPS, LDAP, LDAPS, POP3,
 POP3S, RTMP, RTSP, SCP, SFTP, SMTP, SMTPS, TELNET and TFTP.
 .
 curl supports SSL certificates, HTTP POST, HTTP PUT, FTP uploading, HTTP form
 based upload, proxies, cookies, user+password authentication (Basic, Digest,
 NTLM, Negotiate, kerberos...), file transfer resume, proxy tunneling and a
 busload of other useful tricks.

# Modify curl-config to make it architecture-independent:
# 1. In --static-libs output, replace the output of krb5-config (which
#    currently includes architecture-specific paths) with a call at
#    runtime to krb5-config.  Of course, this will only work correctly
#    if the installed libkrb5-dev matches the architecture of the
#    program you're linking, or if libkrb5-dev is made
#    multiarch-compatible at some point in the future.  For dynamic
#    linking this has no impact.
# 2. In --configure output, replace the architecture-specific paths
#    used for --libdir and --libexecdir with a literal backquoted call
#    to dpkg-architecture.  This is functionally equivalent to the way
#    debhelper actually invokes configure, and indicates to the user
#    (who runs curl-config --configure in order to learn about how the
#    library was compiled) that they are in fact using a multi-arch
#    package.
# 3. Likewise, replace the architecture name used for --build (and
#    build_alias) with a literal backquoted call to dpkg-architecture.
# 4. In --configure output, remove
#    -fdebug-prefix-map=/buildd/specific/random/path=.
