This is reldb, a collection of programs to handle simple relational database
operations.

Shell scripts are stored with a .sh subscript, which is
stripped off upon install.

Edit the Makefile, in particular, set BINDIR to where you want
the binaries and scripts to go. Typing 'make' will compile and install.

Files:

Makefile		The Makefile (did you guess ?)
README			This file
addcol.sh		Script to add named columns to table
addup.c			Adds up some columns (part of subtotal).
bplokk.sh		Version of plokk for large numbers (even text).
check.sh		Checks sanity of named tables.
columnlist.sh		Lists names of columns in table.
compute.c		Computes new values into columns.
count.c			Counts repeated lines (c.f. uniq).
dataplotpre.sh		Reldb interface |Stat's dataplot.
dbdict.sh		Preliminary "data base dictionary"
dbe.add.sh		Add to database.
dbe.change.sh		Change table.
invert.sh		Inverse matrix command (invert).
joinle.c		Special join, good for length distributions.
jointable.sh		Reldb version of join.
math.sh			Compute simple statistics on table.
matrix.c		Go from (frequency,x,y) to matrix.
mulregpre.sh		Reldb interface to |Stat's regress program.
number.sh		Add a column with a linenumber (cf nl).
pairpre.sh		Reldb interface to |Stat's pair program.
plokk.c			Program to select lines according to list.
preplot.sh		Reldb interface to |Stat's dataplot.
project.c		Project columns out of a table.
recode.c		Recode a column according to list.
regress.c		Simple linear regression.
rename.sh		Rename columns.
see.sh			Display tabs etc.
sideview.sh		Display a table sideways.
sorttable.sh		Sort a table.
subtotal.c		Subtotal some columns.
union.sh		Append one table to another

Someone please suggest a better name for this "package".

The directory ../testdb contains some scripts to test the
scripts and programs. Go there and type 'make', possibly after modifying 
BINDIR in the Makefile.
