AUTHOR: Paul Rogers <paulgrogers at lycos dot com> DATE: 2016-02-08 LICENSE: GPL SYNOPSIS: Package manager "pio" (Package Installation Observer) DESCRIPTION: pio is a "timestamper" package manager found useful for (B)LFS installations. It is run once before installation to "take inventory" of defined directories, then again after installation. It observes new/changed subdirectories and files, and builds a script which will safely remove whatever was installed. This "removal" script is the basis for other tricks it will do. Above all, pio is a dis-integrated package manager. It's simply a hands-on tool to be used. It enforces nothing!

One must understand bash to "extend" it or do "maintenance". Have a care; pio makes scripts that WILL remove files! But being bash script, it can be "easily" maintained or extended. It has no unusual dependencies. HINT: Once upon a time there was git, the Guarded Installation Tool, by Ingo Brueckl (ib@wupperonline.de) 14.11.1996. I found it useful for LFS builds & added a few functions. Then Linus made a kernel development management tool he chose to call git. So I changed this script to avoid potential confusion. pio is still almost entirely Ingo's git. Some functionality has been changed. That's my responsibility. Refer to pio-usage for real hints on using pio effectively. pod is a mashup of several ad-hoc scripts I use when building and maintaining my packages, mostly interacting with pio. template is my build script template demonstrating my usage of pio when building (B)LFS systems. ACKNOWLEDGEMENTS: * Ingo Bruekl for the original git-2.16 * Paul Rogers for resurrection, maintenance, and extensions. CHANGELOG: 2016-02-08: PGR original hint/files.
