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
       version)"  or  by  nothing  (if  an  unversioned  dependency  is deemed
       sufficient).

       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 used if id  of
       dependency  template  is not present). The first alternative dependency
       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 field is 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.
