[* 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 always used and will end up being combined with the dependency template referenced by id-of-dependency-template if 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 fields are:
libftp.so.3 libftp3 #MINVER#
| libgl1-mesa-glx #MINVER#
* Build-Depends-Package: libgl1-mesa-dev
