Linux 2.6 - man page for deb-symbols (linux section 5)

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 alter-
       native 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.

EXAMPLES
   Simple symbols file
       libftp.so.3 libftp3 #MINVER#
	DefaultNetbuf@Base 3.1-1-6
	FtpAccess@Base 3.1-1-6
	[...]

   Advanced symbols file
       libGL.so.1 libgl1
       | libgl1-mesa-glx #MINVER#
       * Build-Depends-Package: libgl1-mesa-dev
	publicGlSymbol@Base 6.3-1
	[...]
	implementationSpecificSymbol@Base 6.5.2-7 1
	[...]
