# Script to assert that the man-refs.ent file is in lexicographical
|
||
|
|
# order by section number then by name. Originally by Dima Dorfman,
|
||
|
|
# public domain, 2001.
|
||
|
|
#
|
||
|
|
# This assumes that all the man pages for one section are in one
|
||
|
|
# contiguous block. It will scan the block and make sure that the man
|
||
|
|
# pages are in lexicographical order. Note that it only looks at the
|
||
|
|
# man page entity, not the name, so the dots (.) used in place of
|
||
|
|
# special characters (e.g., "_", "[") won't get expanded. It will not
|
||
|
|
# edit the file in place; only alert the operator to the discrepancy.
|
||
|
|
# Furthermore, once it found something wrong, it will stop, so it may
|
||
|
|
# be necessary to run it more than once per section to make sure
|
||
|
|
# everything is clean.
|
||
|
|

|

# Used to create doc/share/sgml/man-refs.ent rev. 1.85 (dd, 2001/06/30).
