          A small powerful library manager for the HP48G[X]  

LIBMAN is a small and comfortable library creator and splitter. Renames itself
into D<->L and moves to Port 0. The name D<->L reminds you that it may create 
a Library from a directory and conversely. D<->L may be put into any port or
assigned to a key in order to be accessible from each directory. 

If there is no real number in Level 1 then D<->L does D->Lib, i.e., it creates 
a library from the current directory. To support the user who are not familiar 
with library tools it first invokes a dialog box. All library creators look in
the directory at least for the first of the "$-variables" $ROMID, $TITLE and 
$VISIBLE to define the library's Id (a real), its title, and the set of its
visible variables, respectively. More you need not know about these and other 
$-variables like $CONFIG (which controls the warmstart behaviour). $CONFIG is
created automatically - if already present then D<->L assumes familiarity 
with library creation and skips the dialog box. This box expects entries in
some of the mentioned $-variables. Only $ROMID must get an entry. If $VISIBLE
is skipped, all variables will be visible by default; with the empty list all
variables are hidden. The source directory for a library should not contain 
subdirectories and must be different from HOME.

If there is a real n in Level 1 then |D<->L| "splits" the library with ID n 
whenever such a library exists. The generated directory is similar to the 
source directory the library was made from. It contains all above mentioned 
$-variables; if D<->L is applied to this directory then its source library 
is immediately regained. LIBMAN uses library tools due to R. Grevelle. Due
to compact programming and compression LIBMAN needs only 3.9 KB.
