[Xastir] No readme.1st?

[Tyler Allison]

Lots of online documentation and mailing list archives are pointing people
to readme.1st yet I find no evidence of such a file existing anymore.

Im specifically looking for instructions on setting up the propegation of
NWS alerts to RF with Xastir. I know about the nws-stations.txt file but
nothing more specific about it.

...next...

Is there a doc on how someone might generate an APRS message outside of
Xastir and then 'inject' it into the APRS network via Xastir? Im
specifically looking at generating a string of data that I want to send
out via RF and I dont want to have conflicts with the ONE tnc I have
plugged into Xastir. I figure I can either go direct to the com port on
linux (possible locking issues with Xastir, and could get ugly) or I could
have xastir grab the string/file and send it off as a message from my
station. Think of it like you want to write a quick message via 'cat >
file' and you want Xastir to take the contents of 'file' and send it off
to the APRS network.

I was hoping there was some command like 'Xastir-inject [message|file]'

Thanks,
