]]> packages[=null] bump bump command increases the lower limit of your composer.json requirements
to the currently installed versions. This helps to ensure your dependencies do not
accidentally get downgraded due to some other conflict, and can slightly improve
dependency resolution performance as it limits the amount of package versions
Composer has to look at.

Running this blindly on libraries is **NOT** recommended as it will narrow down
your allowed dependencies, which may cause dependency hell for your users.
Running it with --dev-only on libraries may be fine however as dev requirements
are local to the library and do not affect consumers of the package.

To read a config setting:

/opt/project/composer.phar config bin-dir
Outputs: bin

To edit the global config.json file:

You can use this command to bootstrap new projects or setup a clean
version-controlled installation for developers of your project.

php composer.phar create-project vendor/project target-directory [version]

You can also specify the version with the package name using = or : as separator.

php composer.phar update

To limit the update operation to a few packages, you can list the package(s)
you want to update as such:

php composer.phar update vendor/package1 foo/mypackage [...]

You may also use an asterisk (*) pattern to limit the update operation to package(s)
from a specific vendor:

php composer.phar update vendor/package1 foo/* [...]

To run an update with more restrictive constraints you can use:

php composer.phar update --with vendor/package:1.0.*

To run a partial update with more restrictive constraints you can use the shorthand:

php composer.phar update vendor/package:1.0.*

To select packages names interactively with auto-completion use -i.
