(all): Depend on info. Flatten info directory. This undoes the move to one subdirectory per chapter, which was done during Empire 2. The structure doesn't buy us much, as the info name space is flat, and it complicates makefiles. Overhaul info.pl: - It now wants to run in the root of the build tree. - Information on source files and subjects is now stored in makefiles, thus info.pl no longer picks up random junk from the file system. - Clean up Perl anachronisms, in particular use subroutine arguments and results rather than global variables where convenient. - Change format of diagnostics to the common format used by GNU tools, so that Emacs and the like can parse it. - Catch missing .SA. - When creating a new subject file, cowardly refuse to overwrite an existing file. - Subject files contain topics sorted by chapter, then by name. The order of chapters used to depend on how Perl sorts hash keys. Fix it.

The Empire info pages are organized by subject. To get a list of
|
|
subjects, type:
|
|
.EX info
|
|
or
|
|
.EX help
|
|
You can then type:
|
|
.EX info Subject
|
|
to get a list of Empire commands and info topics which are related
|
|
to the Subject that you chose. Note that Subjects always start with a
|
|
capital letter (this is to distinguish them from commands which are
|
|
always lowercase).

|
To get info on the syntax of an Empire command, type:
|
|
.EX info command
|
|
where "command" is the command you're interested in. Note that info
|
|
about Empire command syntax is always specified lower-case.
|
|
.s1
|
|
To get info about some Empire topic, type:
|
|
.EX info Topic
|
|
Where Topic is the name of some Empire topic that you're interested in.
|
|
.s1
|
|
Every Empire command and topic belongs to at least one subject, and in
|
|
some cases more than one.
|
|
.s1
|
|
.EX info all
|
|
This will list all info pages. Warning: this list is long!

As of this writing, some clients shanghai the help command to provide
|
|
help on their own command line extensions, but fail to integrate
|
|
server help. If the help command doesn't work for you, try the info
|
|
command instead.
