# a "dir" file containing all the installed Info files, which we
|
|
# don't have (it would be impure to have a package installation
|
|
# update some global "dir" file). So this wrapper script around
|
|
# "info" builds a temporary "dir" file on the fly. This is a bit
|

# slow (on a cold cache) but not unacceptably so.
