refactor out subprocess.Popen() and getting stdout to new function get_stdout()
factor out get_stdout() to new file util.py,
use util.get_stdout() in piracast.py too
stop hostapd zombieing
put obj/ directories and *.pyc into .gitignore
re-add license notice which I accidentially removed
different cleanups: whitespace, comments
get rid of subprocess.call() - tends to leave zombies
re-add GPL notice which I accidentially deleted
add GPL notice to core_channel.py
small cleanups
more cleanup
add scripts/core and target/core to .gitignore
remove x bits on non-executables
even more cleanup
chmod -x README.md
more cleanup, mostly prints
add .gitignore:
obj
*.pyc
scripts/core
target/core
take care of consistent style re spaces, colons, comments, ...
take care every .py file has GPL notice
take care of file permissions - only executables need +x
fix typo
factor out calling external commands (and retrieving their stdout) to
util.get_stdout()
braino in piracast.py... and I missed "some" parts in wfd.py...
