XCOMM
|
|
XCOMM This is just a sample implementation of a slightly less primitive
|
|
XCOMM interface than xinit. It looks for user .xinitrc and .xserverrc
|
|
XCOMM files, then system xinitrc and xserverrc files, else lets xinit choose
|
|
XCOMM its default. The system xinitrc should probably do things like check
|
|
XCOMM for .Xresources files and merge them in, start up a window manager,
|
|
XCOMM and pop a clock and several xterms.
|
|

|
|
XCOMM Site administrators are STRONGLY urged to write nicer versions.

#ifdef __APPLE__

XCOMM Check for /usr/bin/X11 and BINDIR in the path, if not add them.
|
|
XCOMM This allows startx to be placed in a place like /usr/bin or /usr/local/bin
|
|
XCOMM and people may use X without changing their PATH.
|
|
XCOMM Note that we put our own bin directory at the front of the path, and
|
|
XCOMM the standard system path at the back, since if you are using the Xorg
|
|
XCOMM server there's a pretty good chance you want to bias the Xorg clients
|
|
XCOMM over the old system's clients.
|
|
|
|
XCOMM First our compiled path

XCOMM Bourne shell does not automatically export modified environment variables
