2 """ IPython extension: add %rehashdir magic
3
4 Usage:
5
6 %rehash_dir c:/bin c:/tools
7 - Add all executables under c:/bin and c:/tools to alias table, in
8 order to make them directly executable from any directory.
9
10 This also serves as an example on how to extend ipython
11 with new magic functions.
12
13 Unlike rest of ipython, this requires Python 2.4 (optional
14 extensions are allowed to do that).
15
16 To install, add
17
18 "import_mod rehash_dir"
19
20 To your ipythonrc or just execute "import rehash_dir" in ipython
21 prompt.
