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 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-shlib‐
deps to make sure that the dependency generated is at least as strict
as the corresponding build dependency.
