| 55 | 1.3 The Package Manager</A> |
| 56 | </H1> |
| 57 | |
| 58 | <P> |
| 59 | Historically MacPython came with a number of useful extension packages |
| 60 | included, because most Macintosh users do not have access to a development |
| 61 | environment and C compiler. For Mac OS X that bundling is no longer done, |
| 62 | but a new mechanism has been made available to allow easy access to |
| 63 | extension packages. |
| 64 | |
| 65 | <P> |
| 66 | The Python Package Manager helps you installing additional packages |
| 67 | that enhance Python. It determines the exact MacOS version and Python |
| 68 | version you have and uses that information to download a database that |
| 69 | has packages that are tested and tried on that combination. In other |
| 70 | words: if something is in your Package Manager window but does not work |
| 71 | you are free to blame the database maintainer. |
| 72 | |
| 73 | <P> |
| 74 | PackageManager then checks which of the packages you have installed and |
| 75 | which ones are not. This should also work when you have installed packages |
| 76 | outside of PackageManager. You can select packages and install them, |
| 77 | and PackageManager will work out the requirements and install these too. |
| 78 | |
| 79 | <P> |
| 80 | Often PackageManager will list a package in two flavors: binary and |
| 81 | source. Binary should always work, source will only work if you have |
| 82 | installed the Apple Developer Tools. PackageManager will warn you about |
| 83 | this, and also about other external dependencies. |
| 84 | |
| 85 | <P> |
| 86 | PackageManager is available as a separate application and also as a |
| 87 | function of the IDE, through the File->Package Manager menu entry. |
