# Create an empty CPAN-like repository in directory ~/mypan
$ pinto-admin -r ~/mypan create

# Get the current version of Plack (and all its dependencies) into the repository
$ pinto-admin -r ~/mypan import Plack

# Suppose HTTP::Simple has a bug and you made your own patch as HTTP-Simple-0.23-PATCHED.tar.gz
$ pinto-admin -r ~/mypan add HTTP-Simple-0.23-PATCHED.tar.gz

# Point cpan(1) or cpanm(1) at your repository, to install Plack with your patched HTTP::Simple
# cpanm --mirror file:///home/you/mypan --mirror-only Plack

# Time passes...and now we decide we want to upgrade the latest Plack, which is now Plack-2.4
$ pinto-admin -r ~/mypan import Plack-2.4

# It seems that bug in HTTP::Simple has now been fixed.  So we can remove our patched version
$ pinto-admin -r ~/mypan remove HTTP-Simple-0.23-PATCHED.tar.gz
