Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.

/**

|
** This comment is a little out of context here, but it contains
|
|
** some useful information...
|
|
********************************************************************
|
|
**
|
|
** The following lines take care of the Logitech MouseMan protocols.
|
|
**
|
|
** NOTE: There are different versions of both MouseMan and TrackMan!
|
|
** Hence I add another protocol P_LOGIMAN, which the user can
|
|
** specify as MouseMan in his XF86Config file. This entry was
|
|
** formerly handled as a special case of P_MS. However, people
|
|
** who don't have the middle button problem, can still specify
|
|
** Microsoft and use P_MS.
|
|
**
|
|
** By default, these mice should use a 3 byte Microsoft protocol
|
|
** plus a 4th byte for the middle button. However, the mouse might
|
|
** have switched to a different protocol before we use it, so I send
|
|
** the proper sequence just in case.
|
|
**
|
|
** NOTE: - all commands to (at least the European) MouseMan have to
|
|
** be sent at 1200 Baud.
|
|
** - each command starts with a '*'.
|
|
** - whenever the MouseMan receives a '*', it will switch back
|
|
** to 1200 Baud. Hence I have to select the desired protocol
|
|
** first, then select the baud rate.
|
|
**
|
|
** The protocols supported by the (European) MouseMan are:
|
|
** - 5 byte packed binary protocol, as with the Mouse Systems
|
|
** mouse. Selected by sequence "*U".
|
|
** - 2 button 3 byte MicroSoft compatible protocol. Selected
|
|
** by sequence "*V".
|
|
** - 3 button 3+1 byte MicroSoft compatible protocol (default).
|
|
** Selected by sequence "*X".
|
|
**
|
|
** The following baud rates are supported:
|
|
** - 1200 Baud (default). Selected by sequence "*n".
|
|
** - 9600 Baud. Selected by sequence "*q".
|
|
**
|
|
** Selecting a sample rate is no longer supported with the MouseMan!
|
|
** Some additional lines in xf86Config.c take care of ill configured
|
|
** baud rates and sample rates. (The user will get an error.)
