WebSubmit: Web-based Applications with Tcl

WebSubmit is a Web-based framework providing seamless access to applications on a collection of heterogeneous computing systems. Strong authentication methods allow users to execute tasks on remote systems as if they were directly connected. Each application is presented as an HTML form; this form is lled out and submitted to the server, which then processes the request and executes the desired tasks (as the current user) on the speciied remote system. The software is implemented as a collection of Tcl CGI scripts and a large body of Tcl support code. Tcl packages and namespaces are used to encapsulate functionally-distinct bodies of code, and create a system that is exible, extensible, and modular.
