** What is this software good for? **
You can make a set of simple static web pages containing a title and set of thumbnails with file names of JPG photos in a directory on your computer. You can even process a whole tree of directories at once. This is all the scripts do.
You can then do with the result whatever you want, like upload the whole directory on web and use it as part of a web photo gallery, use it to create index print of photos, or burn it on CDROM, but it is up to you and you need other tools to do these tasks.
** Will it run on my system? **
This software is a set of Bash shell scripts. This means it will work only in an environment with Bash shell installed. It is pre-installed on most of nowadays Linux distributions, I believe it is part of Mac OS X.
It also needs few common Unix tools (see html documentation in /usr/doc/pgg-<version> for details).
On Windows, you first need to install an software containing Unix tools, I have tested it with Cygwin. It is probably an overkill to go to install Cygwin just to generate set of static html pages (you will probaly find suitable Windows native app for it), but it is great way to start familiarize yourself with Unix tools without the need of leaving Windows.
** How do I install it? **
If you have rpm based Linux, it should be installable via double clicking the rpm file.
Other systems:
Unpack the package with an archive manager supporting it (try just doubleclicking the package), and copy the files to appropriate locations (administrative privileges needed), i.e. what is in the archive in usr/bin to /usr/bin and so on. It is possible to use other locations for bin a and doc folders (in the /usr/local tree for example), except the /usr/share/pgg location - it could not be changed without modifying the sources of the scripts. With files in usr/bin make sure they have execute permission.
On Windows with Cygwin the files go into the Cygwin folder and appropriate subfolders.
** How do I use it? **
See html documentation in /usr/doc/pgg-<version>. The program is supposed to be used from terminal (Cygwin console on Windows, not the regular Windows terminal).
