->setHelp(<<<'EOF'
The <info>%command.name%</info> command extracts translation strings from templates
of a given bundle or the default translations directory. It can display them or merge
the new ones into the translation files.
When new translation strings are found it can automatically add a prefix to the translation
message.
Example running against a Bundle (AcmeBundle)
<info>php %command.full_name% --dump-messages en AcmeBundle</info>
<info>php %command.full_name% --force --prefix="new_" fr AcmeBundle</info>
Example running against default messages directory
<info>php %command.full_name% --dump-messages en</info>
<info>php %command.full_name% --force --prefix="new_" fr</info>
You can sort the output with the <comment>--sort</> flag:
<info>php %command.full_name% --dump-messages --sort=asc en AcmeBundle</info>
<info>php %command.full_name% --dump-messages --sort=desc fr</info>
You can dump a tree-like structure using the yaml format with <comment>--as-tree</> flag:
<info>php %command.full_name% --force --format=yaml --as-tree=3 en AcmeBundle</info>
