This is a teacup subcommand.
From the supplied help:
link -- Manage links between installation repositories and tcl shells
teacup.exe link make PATH SHELL : Create a connection between the installation repository at PATH and the tcl shell (aka tclsh) SHELL. From then on, the SHELL will search the repository at PATH when a package require is invoked, and the repository knows that SHELL is one of its users. The latter means that teacup.exe will check SHELL' when attempting to install a package.
LV Can someone expound on what the sentence about teacup checking SHELL means? Also, how do you determine what value should be used for PATH?
teacup.exe link cut (PATH|SHELL) (PATH|SHELL) ...
Removes the connection between the installation repository at PATH and the tcl shell SHELL. From then on the SHELL will _not_ search the repository when a package is required, and teacup.exe will not check the shell anymore when installing a package.
Note that it is allowed to specify an arbitrary number of SHELLs and repository PATHs, in arbitrary order, in one invocation of teacup link cut. The command will disconnect all possible pairs.
teacup.exe link info PATH|SHELL
Prints either the list of shells the repository at PATH is connected to, or the list of repositories the SHELL is using.
NOTE:
For PATH: provide the path to teapot.local-ma.config. teacup link outputs the associated SHELL(s) path.
For SHELL: provide the path to tclsh85.exe or any other version. teacup link outputs the associated repository PATH (must be unique).
