I don't know how else to describe it, that is so cool :)
[code]
#!/usr/bin/python

import textwrap
data = {'CBUILD':None, 'CFLAGS':None, 'MAKEOPTS':None}
def get_use():
     fname = open('/tmp/comprookie2000/emerge_info.txt')
     for line in fname:
         for keyphrase in data:
             if keyphrase in line:
                 output = line.split('"')[1]
                 data[keyphrase] = textwrap.fill(output, 80)
     fname.close()

get_use()

CBUILD = data['CBUILD']
CFLAGS = data['CFLAGS']
MAKEOPTS = data['MAKEOPTS']


print 'CBUILD =',CBUILD
print 'CFLAGS =',CFLAGS
print 'MAKEOPTS =',MAKEOPTS


[output]
CBUILD = x86_64-pc-linux-gnu
CFLAGS = -march=opteron -O2 -pipe
MAKEOPTS = -j3

Thanks Alan Martin, Sander, hope I did it correctly.
