33 | guile-tools [OPTION] PROGRAM [ARGS] | |

35 | If PROGRAM is "list" or omitted, display contents of scripts dir, otherwise | |
36 | PROGRAM is run w/ ARGS. Options (only one of which may be used at a time): | |
37 | --scriptsdir DIR -- Look in DIR for scripts | |
38 | --guileversion VERS -- Look in $pkgdatadir/VERS/scripts for scripts | |
d902b02a | 39 | --source -- Display PROGRAM source (ignore ARGS) to stdout |
