texinode(The comp1 Module)(The compctl Module)(The clone Module)(Zsh Modules) sect(The comp1 Module) The tt(comp1) module does nothing that is visible to the user. Its purpose is to provide the internal basis of the programmable completion mechanism. This module must be loaded before any module that provides a means of controlling completion (such as the tt(compctl) module), or that uses completions (such as the tt(zle) module). This is done automatically for modules distributed with zsh, and for other modules can be effected by the use of tt(zmodload -d).
