21 | * Program: addpm (adds emacs to the Windows program manager) | |

23 | * Usage: | |
2cc1905e | 24 | * argv[1] = install path for emacs |
84ef4ca2 JR |
25 | * |
26 | * argv[2] used to be an optional argument for setting the icon. | |
27 | * But now Emacs has a professional looking icon of its own. | |
28 | * If users really want to change it, they can go into the settings of | |
29 | * the shortcut that is created and do it there. | |
