The actualy lintian code is:

foreach my $expected_name (@sonames) {
$expected_name =~ s/([0-9])\.so\./$1-/;
$expected_name =~ s/\.so(?:\.|\z)//;
$expected_name =~ s/_/-/g;
if ((lc($expected_name) eq $pkg)
|| (lc($expected_name) eq $base_pkg)) {
$match_found = 1;
last;
}
}

This can be translated to the following sed command:

LC_ALL=C sed -r -e's/([0-9])\.so\./\1-/; s/\.so(\.|$)//; y/_/-/; s/(.*)/\L&/'

And presumably also needs the:

objdump -p /path/to/libfoo-bar.so.1.2.3 | sed -n -e's/^[[:space:]]*SONAME[[:space:]]*//p'

part to extract the SONAME in the first place.

Sean and I talked about this at DebConf and agreed that it made sense to
add this footnote now, although it would still be great if there were some implementation of this elsewhere we could just point to.

I've applied the following, which also fixes some formatting issues (we'd
lost the italics on soversion).

Run-time shared libraries

-The run-time shared library must be placed in a package whose name
-changes whenever the ``SONAME`` of the shared library changes. This
-allows several versions of the shared library to be installed at the

-library without immediately breaking binaries that depend on the old
-version. Normally, the run-time shared library and its ``SONAME``
-symlink should be placed in a package named librarynamesoversion, where -soversion is the version number in the ``SONAME`` of the shared library. -Alternatively, if it would be confusing to directly append soversion to -libraryname (if, for example, libraryname itself ends in a number), you -should use libraryname-soversion instead.
