pipe_tasks is a package in the LSST Science Pipelines.
pipe_tasks provides many of the Task classes that drive the LSST Science Pipelines. The command-line tasks listed here are useful data processing entry points for most users. These scripts can be found in the bin.src/ folder. After building and installing the package, they can also be found in the created bin/ folder.
The repository also contains several Pipelines used for processing. You can also assemble your own pipelines by combining individual tasks through their Python APIs.
pipe_tasks does not provide all the tasks and command-line tasks in the LSST Science Pipelines. Tasks can be found in many other high-level packages in the Science Pipelines, such as ip_isr.
To learn more about the task framework in general, see the lsst.pipe.base module documentation.
The package namespace itself is mostly empty. Each specific processing tool must be imported directly from the module; for instance,
from lsst.pipe.tasks.processCcd import ProcessCcdTask
