Changes:
|
||||
=======
|
||||
|
||||
v1.1: (29 May 94)
|
||||
Makewhatis will now ignore any man page starting with ".so", in
|
||||
order to eliminate multiple files. The resultant blank lines in
|
||||
the whatis database have therefore been eliminated.
|
||||
|
||||
Changed -v flag to {-v1|-v2} for differing stages of verbosity.
|
||||
Only error output will be logged with the -l flag.
|
||||
|
||||
Manual page was updated, to include a correction to the -o flag usage
|
||||
and the modification to the -v flag. Descriptions of bugs unlikely
|
||||
to be fixed were added. Date and version were changed.
|
||||
|
||||
Fixed bug where input buffer wasn't properly terminated, and added
|
||||
checks for buffer overflows.
|
||||
|
||||
Makewhatis will now display all commands about which the manual page
|
||||
is written. For example, if foo.1 described both foo(1) and bar(1),
|
||||
and bar.1 was an .so (or .l) link to foo.1, then the database entry
|
||||
will have changed from
|
||||
foo (1) - extract and add thingys from the bork stream
|
||||
to
|
||||
foo, bar (1) - extract and add thingys from the bork stream
|
||||
|
||||
Makewhatis used to pick up the first NAME string in the file as a reference
|
||||
point. Now, any NAME is ignored in any line starting with .\" or .TH
|
||||
|
||||
Filename chapter numbers will now be correctly extracted regardless of the
|
||||
existence of .Z, .z, .F, or .f suffixes, or of the existence of '.' within
|
||||
the base file name.
|
||||
|
||||
Makewhatis is now linked with Soenke's gnulib for the getopt() function,
|
||||
rather than using the libc version.
|
||||
|
||||
Stack usage was reduced to 1k. Be aware, though, that a fair amount
|
||||
of global storage is used, including three 1k buffers.
|
||||
|
||||

||||

Instead, if item2.l and item3.l are links to item1.3, the created record reads

.nf

item1 (3) - This is the description.
