Setting BASH_IMPORT_PATH in an .rc file is not less confusing than simply setting PATH in the same .rc file. In the case one mix'n'match dir setup in both PATH and BASH_IMPORT_PATH, and in case of mix'n'match -x more setting of a .sh files, then all sort of documentation must be done to explicitly tells which case takes precedence etc... I prefere by far to handle $PATH myself in my .rc and place myself my 'shell packages' in my hierarchies. Note that a package (an import) generally is non executable, as some mentioned, yet beeing able to 'run' a package can be interesting in some case, for instance a pacakge run can display its embedded documentation, useful during development (yet debatable) My package management have the same feature as @Koichi one, i.e a C like #pragma once. I add a 'force' option to my 'import', this is for interactive 'import', to bring more functions (global, alias), yet during bring-up one may fix a package an force a reload. Some packages, on the other hand, are to be used 'imported' by other packages and as such I have versioning mechanism, so 'import' can tell about new version available from the git repos, or even an auto update from git (when suitable) etc... and indeed it is possible for the import to tell which minimal version is needed for the 'import'. So doing an 'import' feature, may be to be on par with python/perl/nameit, require more than just a new ENV var and the hack to use it. Cheers
