# ur(1p)

command-line interface to UR

## NAME

ur - command-line interface to UR

## DESCRIPTION

The **ur** command is the entry point for a suite of tools to create and manage a module tree of UR classes, data sources, and views.

It also includes launchers for some built-in services.

## SUB-COMMANDS

See the help on specific sub-commands for details.

```
 init      NAMESPACE [DB]      initialize a new UR app in one command
 define    ...                 define namespaces, data sources and classes
 describe  CLASSES-OR-MODULES  show class properties, relationships, meta-data
 update    ...                 update parts of the source tree of a UR namespace
 list      ...                 list objects, classes, modules
 sys       ...                 service launchers
 test      ...                 tools for testing and debugging
```

## DEVELOPMENT

### PWD

Running this WITHIN the source tree of a UR namespace will automatically "use lib" your tree.

A message will appear to STDERR when this occurs.  See the \<above\> module for context-sensitive library usage info.

### MAC SOFTWARE MODULE API

Looking for the docs on UR.pm on a Mac?

Try "perldoc UR.pm" or "man UR".  On some systems (Mac), perldoc will show this page for both "perldoc ur" and also "perldoc UR" due to filesystem case insensitivity.
