NAME
ratcl - A Relational Algebra extension for Tcl

SYNOPSIS
package require ratcl ?4?

view arg operator ... | ...

DESCRIPTION

The ratcl package implements a general-purpose relational algebra and persistence framework as a notation on top of the Vlerq extension.

COMMANDS

view arg operator ... | ...
    The view command wraps all the different operators provided by the vlerq package and lets you create pipelines, whereby the output of one operator is fed as input to the next.

Return a list with all the column names of view.

The open operator opens a Metakit-compatible datafile and returns
    its root view.

Store a view in the varname variable.
    That same view is also returned as result.
