I use two scripts to use tags and cscope in conjunction with the oft
overlooked fact that the linux makefiles include makefiles with tags and
cscope targets : i just run "tags" .....

1) ~/bin/tags

,----
| #!/bin/bash
| cd ~/programming
| echo Calculating tags in ~/programming ...
| ctags-exuberant  -e --language-force=auto --recurse=yes --links=yes ~/programming
| 
| cd /usr/src/linux
| echo Calculating tags in /usr/src
| make TAGS
| 
| ~/bin/makecs
| # echo Done!
`----

2) ~/bin/makecs

,----
| #!/bin/bash
| 
| SRC=/usr/src/linux
| 
| cd $SRC
| echo "CScoping Linux sources ....."
| make cscope
| 
| SRC=/home/rgr/programming
| 
| cd $SRC
| echo "CScoping ~/programming/c....."
| # find -L $SRC -name "*.[chxsS]" -o -iname \*.php -print > cscope.files
| find -L $SRC -name "*.[chxsS]" -print > cscope.files
| cscope -b -q -u
