| A <<//versioned-package-id//>> is the combination of a package identifier (found using the ''vpkg_list'' command) with a version/variant identifier (via the ''vpkg_versions'' command). The two pieces are joined using a forward slash (/). For example, the commercial software "Matlab" has a <<//package-id//>> of ''matlab'' and the 2012 release has a <<//version-id//>> of ''r2012a'', producing the <<//versioned-package-id//>> ''matlab/r2012a''. | A <<//versioned-package-id//>> is the combination of a package identifier (found using the ''vpkg_list'' command) with a version/variant identifier (via the ''vpkg_versions'' command).

| <note>In the context of a <<//versioned-package-id//>>, a blank <<version-id>> implies the default version of the package. If the 2012 release of Matlab were the default, then using ''matlab'' (or ''matlab/default'') as the <<versioned-package-id>> would imply ''matlab/r2012a''.</note> | <note>In the context of a <<//versioned-package-id//>>, a blank <<//version-id//>> implies the default version of the package (marked with an asterisk ''*'').

| VALET environment changes apply to the shell in which the ''vpkg_require'' command is issued; the changes do not "stick" after exiting that shell (by logging-out, for example). Thus, one way to discard changes affected by a ''vpkg_require'' command is to just exit the shell. The ''vpkg_rollback'' command is a more graceful alternative and iteratively discards the changes produced by prior ''vpkg_require'' commands issued in the shell. To undo all changes, ''vpkg_require all'' can be used. | VALET environment changes apply to the shell in which the ''vpkg_require'' command is issued; the changes do not "stick" after exiting that shell (by logging-out, for example).
