a6bbb732b27b Added .hgeol file to automatically convert line endings. KarstenBock@gmx.net parents: 41 diff changeset	14 Modes manage the state and transition between different application modes.
a6bbb732b27b Added .hgeol file to automatically convert line endings. KarstenBock@gmx.net parents: 41 diff changeset	15 Typically such modes are presented as different screens that the user can
a6bbb732b27b Added .hgeol file to automatically convert line endings. KarstenBock@gmx.net parents: 41 diff changeset	16 navigate between, similar to the way a browser navigates web pages. Individual
a6bbb732b27b Added .hgeol file to automatically convert line endings. KarstenBock@gmx.net parents: 41 diff changeset	17 modes may be things like:

a6bbb732b27b Added .hgeol file to automatically convert line endings. KarstenBock@gmx.net parents: 41 diff changeset	25 The modal framework provides a simple mechanism to ensure that modes are
