If we provide a mandoc-style manpage, we must also provide it
pre-formatted, for Solaris and some other operating systems that cannot
render it.

Whenever two + files are found that match exactly, the two files are linked (soft or + hard) together. + + GGooaall + The goal of this program is to conserve disk space when you have several + different trees of large projects on your disk. By creating hardlinks or + softlinks between the files that are the same, you can save lots of disk + space. For example, two different versions of the Linux kernel only dif- + fer in a small number of files. By running this program you only need to + store the contents of those files once. This is especially useful if you + have different versions of complete trees lying around. + + IImmpplleemmeennttaattiioonn + The filesize of every file is used as an indication of wether two files + can be the same. Whenever the filesizes match, the hashes of these two + files are compared. Whenever these match, the file contents are compared. + For every matching pair one of the two files is replaced by a hard link + to the other file. With the -s option a softlink is used. + + To allow you to do this incrementally, the "rm" is done on the file with + the least links. This allows you to "merge" a new tree with several trees + that have already been processed. The new tree has link count 1, while + the old tree has a higher link count for those files that are likely can- + didates for linkage. + + The current implementation keeps the "first" incantation of a file, and + replaces further occurrances of the same file.
