=head1 NAME
dh_installcliframework - install development links into framework paths
=cut
use strict;
use Debian::Debhelper::Dh_Lib;
=head1 SYNOPSIS
B<dh_installcliframework> [S<I<debhelper options>>] [B<-n>]
=head1 DESCRIPTION
dh_installcliframework is a debhelper program that is responsible for
installing assemblies and related files used by the Debian cli-common
package into the framework paths.
This is useful for third-party languages, such as F#, that add an automatic
reference a core library in the same way that B<mcs> adds an automatic
reference to B<mscorlib>.
The format of a C<installcliframework> file is line based, treating any line
starting with '#' as a comment. The first component of each line specifies the
framework version to install to, multiplied by 10 to get an integer. The second
component is the full path of the file to install into the framework path.
dh_installcliframework only installs links for compile-time assembly resolution;
it does B<not> provide any support for runtime assembly resolution, which is
the responsibility of the GAC. Any assembly reference installed by
dh_installcliframework will also need to be installed into the GAC. See
L<dh_installcligac(1)> for how to do this.
Note that, unlike the GAC, there is no mechanism for multiple versions of the
same assembly to be installed into the framework paths. This means that it is
usually incorrect for a package to call both dh_installcligac and
dh_installcliframework.
If the files installed by dh_installcliframework are provided by binary
packages built from the same source package then appropriate dependencies
are generated into the C<cli:Depends> field.
It also automatically generates the postinst and prerm commands needed
to late install the assemblies. See L<dh_installdeb(1)> for an
explanation of how this works.
This is based on L<dh_installemacsen(1)> in the emacsen-common package.
=head1 EXAMPLE
=over 4
# Example debian/pkgfoo.installcliframework file
# This is a comment.
# Blank lines are ignored:
# This assembly is installed into the .NET 4.0 framework path
# (usually /usr/lib/mono/4.0/):
40 /usr/lib/cli/pkgfoo/Foo.dll
# This assembly is installed into the .NET 3.5 framework path:
35 /usr/lib/cli/pkgfoo/Bar.dll
# You can also install ancilliary files, if needed:
40 /usr/lib/cli/pkgfoo/Foo.dll.optdata
# It is valid to install the same file for different framework versions:
40 /usr/lib/cli/pkgfoo/Baz.dll
45 /usr/lib/cli/pkgfoo/Baz.dll

=head1 OPTIONS
=over 4
=item B<-n>, B<--noscripts>
Do not modify postinst/prerm scripts.

=head1 NOTES
Note that this command is not idempotent. "dh_prep" should be called
between invocations of this command. Otherwise, it may cause multiple
instances of the same text to be added to maintainer scripts.
