=head1 NAME

C<TeXLive::TLPostActions> -- TeX Live Post Installation and Removal Routines

=head1 SYNOPSIS

  use TeXLive::TLPostActions;

=head1 DESCRIPTION

The L<TeXLive::TLPostActions> module exports the C<%PostInstall> and
the C<%PostRemove> hash indexed by package names providing code references.

These code references are called with the root of the installation as
argument (C<$SELFAUTOPARENT>). Additional arguments, but not necessarily
present, are the value of C<TEXMFSYSVAR> and C<TEXMFLOCAL>.

=head1 SEE ALSO

The modules L<TeXLive::TLUtils>, L<TeXLive::TLPSRC>,
L<TeXLive::TLPDB>, L<TeXLive::TLTREE>, L<TeXLive::TeXCatalogue>.
