|
33 # enough to only build what has changed. It can be confused, however, |
|
34 # if files are renamed or removed, so it may be necessary to manually |
|
35 # remove cscope.out if a lot of reorganization has occurred. |

79 # (.del files are created by sccsrm, demo directories contain many .java files |

|
81 # duplicates of files within the source hierarchy). The ordering of the .raw |

82 # file is an attempt to make cscope display the most relevant files first. |
