# Usage: $0 <includedir>
|

#
|

# Purpose:
|

|
|
# Remove old header files by comparing list of headers generated
|
||
|
|
# on the fly against headers already existing under <includedir>
|
||
|
|
#
|
||
|
|
# Assumptions:
|
||
|
|
# All directories under (and including) <includedir> have a list
|
||
|
|
# of headers in the file .headerlist-<nameofsubdir>.
