NAME
       deb-symbols - Debian's extended shared library information file

SYNOPSIS
       symbols

DESCRIPTION
       The  format for an extended shared library dependency information entry
       in these files is:

       library-soname main-dependency-template
       [| alternative-dependency-template]
       [...]
       [* field-name: field-value]
       [...]
        symbol minimal-version [id-of-dependency-template]

       The library-soname is exactly the value of the SONAME field as exported
       by  objdump(1). A dependency-template is a dependency where #MINVER# is
       dynamically replaced either by a version check like  "(>=  minimal-ver-
       sion)"  or  by  nothing  (if an unversioned dependency is deemed suffi-
       cient).

       Each exported symbol (listed as name@version, with version being "Base"
       if  the library is not versioned) is associated to a minimal-version of
       its dependency template (the main dependency template  is  always  used
       and  will end up being combined with the dependency template referenced
       by id-of-dependency-template if present). The first alternative  depen-
       dency template is numbered 1, the second one 2, etc.

       Each entry for a library can also have some fields of meta-information.
       Those fields are stored on lines starting with an asterisk.  Currently,
       the only valid fields are:

       Build-Depends-Package
              It  indicates  the  name of the "-dev" package associated to the
              library and is used by dpkg-shlibdeps  to  make  sure  that  the
              dependency  generated is at least as strict as the corresponding
              build dependency.

       Ignore-Blacklist-Groups
              It indicates what blacklist  groups  should  be  ignored,  as  a
              whitespace  separated  list,  so  that  the symbols contained in
              those groups get included in the output file. This  should  only
              be  necessary for toolchain packages providing those blacklisted
              symbols. The available groups are system dependent, for ELF  and
              GNU-based systems these are aeabi and gomp.
