- the old compiler splits source files on a domain by domain basis
-
- the new compiler compiles all of the domains in a file together into a
- single output file
-
- in order to converge these two approaches nrlibs are being combined on
- a file basis rather than split on a domain basis. this change should be
- transparent to all code that properly accesses the files.
-
- INTERP.EXPOSED will be enhanced to contain the source file name of
- the domain. thus, instead of:
-    INT                             Integer
- it will be:
-    INT   integer                   Integer
-
- which would mean that the library that contains INT would be integer.NRLIB
- by using this mechanism we can continue to use the old libraries 
- since each entry would now contain:
-    INT   INT                       Integer
- which would mean that the library that contains the domain INT is INT.NRLIB
-
- old file formats for nrlibs:
-
- first sexpr is integer specifying the byte position of the index of the file
- next n sexprs are information in the nrlib
- last sexpr is an alist (pointed at by the first number in the file) which
- contains triples. e.g. (("slot1info" 0 2550)...)
- each triple consists of a string, a zero, and an byte offset into the file
- of the information requested e.g. slot1info starts at byte 2550
-
- new file formats for libs:
-
- first sexpr is either an integer (in which case this is exactly an old nrlib
-       --- or ---
- first sexpr is an alist of the form:
- ((abbreviation . index) ...)
- where each abbreviation is the abbreviation of the domain name and each
- index is a pointer to the triples alist
-
- so, for example, integer.spad contains 5 domains:
-  INTSLPE, INT, NNI, PI and ROMAN
- previously INT.NRLIB/index.KAF contained:
- 2550  
- (sexpr1...) 
- (sexpr2....) 
- (sexpr3...) 
- (("sexpr1" 0 8) ("sexpr2" 0 22) ("sexpr3 0 45))
- and the individual index.KAF files were similar for the other 4 domains.
-
- under the new scheme integer.nrlib/index.KAF would contain:
- ((INTSLPE . 2000) (INT . 4000) (NNI . 6000) (PI . 8000) (ROMAN . 10000))
- (sexpr1...)       --- info for INTSLPE
- (sexpr2....) 
- (sexpr3...) 
- (("sexpr1" 0 8) ("sexpr2" 0 22) ("sexpr3 0 45))
- (sexpr1...)       --- info for INT
- (sexpr2....) 
- (sexpr3...) 
- (("sexpr1" 0 2800) ("sexpr2" 0 2900) ("sexpr3 0 3000))
- (sexpr1...)       --- info for NNI
- (sexpr2....) 
- (sexpr3...) 
- (("sexpr1" 0 4100) ("sexpr2" 0 4200) ("sexpr3 0 4300))
- (sexpr1...)       --- info for PI
- (sexpr2....) 
- (sexpr3...) 
- (("sexpr1" 0 6100) ("sexpr2" 0 6200) ("sexpr3 0 6300))
- (sexpr1...)       --- info for ROMAN
- (sexpr2....) 
- (sexpr3...) 
- (("sexpr1" 0 8100) ("sexpr2" 0 8200) ("sexpr3 0 8300))
-
- when an NRLIB is opened currently the position information is first
- read into the libstream-indextable slot, then this information is
- overwritten by the index table itself.
-
- we need the name of the NRLIB passed down to the low level functions
- so they can open the new NRLIB format and perform the correct file
- position operation. once the NRLIB is open it is only referenced
- within one constructor so we can lose the master index table.

-; in the old system each constructor (e.g. LIST) had one library directory
-; (e.g. LIST.NRLIB). this directory contained a random access file called
-; the index.KAF file. the interpreter needed this KAF file at runtime for
-; two entries, the operationAlist and the ConstructorModemap.
-; during the redesign for the new compiler we decided to merge all of
-; these .NRLIB/index.KAF files into one database, CONSTRUCT.DAASE.
-; requests to get information from this database are intended to be
-; cached so that multiple references do not cause additional disk i/o.
-; this database is left open at all times as it is used frequently by
-; the interpreter. one minor complication is that newly compiled files
-; need to override information that exists in this database. 
-;   the design calls for constructing a random read (KAF format) file
-; that is accessed by functions that cache their results. when the
-; database is opened the list of constructor-index pairs is hashed
-; by constructor name. a request for information about a constructor
-; causes the information to replace the index in the hash table. since
-; the index is a number and the data is a non-numeric sexpr there is
-; no source of confusion about when the data needs to be read.
-;
-; the format of this new database is as follows:
-;
-;first entry:
-; an integer giving the byte offset to the constructor alist
-; at the bottom of the file
-;second and subsequent entries (one per constructor)
-; (operationAlist)
-; (constructorModemap)
-; (("operationAlist" 0 index) ("constructorModemap" 0 index))
-;last entry: (pointed at by the first entry)
-; an alist of (constructor . index) e.g.
-;   ((PI . index) (NNI . index) ....) ...)
-; this list is read at open time and hashed by the car of each item.
-
-
-; this is a hashtable which is indexed by constructor name (eg PI) and
-; returns the constructorModemap or the index into the construct.daase
