deb-shlibs(5)             (2021-04-13)              deb-shlibs(5)

     NAME
          deb-shlibs - Debian shared library information file

     SYNOPSIS
          debian/shlibs, debian/binary-name.shlibs, DEBIAN/shlibs

     DESCRIPTION
          shlibs files map shared library names and versions (SONAMEs)
          to dependencies suitable for a package control file.  There
          is one entry per line. Blank lines are not allowed.  Lines
          beginning with an # character are considered commentary, and
          are ignored.  All other lines must have the format:

              [type:] library version dependencies

          The library and version fields are whitespace-delimited, but
          the dependencies field extends to the end of the line.  The
          type field is optional and normally not needed.

          The dependencies field has the same syntax as the Depends
          field in a binary control file, see deb-control(5).

     SONAME FORMATS
          The SONAME formats supported are:

              name.so.version

          and

              name-version.so

          where name is usually prefixed by lib.

     EXAMPLES
          The shlibs file for a typical library package, named
          libcrunch1, that provides one library whose SONAME is
          libcrunch.so.1, might read

           libcrunch 1 libcrunch1 (>= 1.2-1)

          The dependencies must mention the most recent version of the
          package that added new symbols to the library: in the above
          example, new symbols were added to version 1.2 of libcrunch.
          This is not the only reason the dependencies might need to
          be tightened.
