Patchutils contains a collection of tools for manipulating patch files: interdiff, combinediff, flipdiff, filterdiff, fixcvsdiff, rediff, lsdiff, grepdiff, splitdiff, recountdiff, and unwrapdiff. You can use interdiff to create an incremental patch between two patches that are against a common source tree, combinediff for creating a cumulative diff from two incremental patches, and flipdiff to transpose two incremental patches. Filterdiff is for extracting or excluding patches from a patch set based on modified files matching shell wildcards. Lsdiff lists modified files in a patch. Rediff, recountdiff, and unwrapdiff correct hand-edited (or otherwise broken) patches.
portreserve aims to help services with well-known ports that lie in the bindresvport() range. It prevents portmap (or other programs using bindresvport()) from occupying a real service's port by occupying it itself, until the real service tells it to release the port (generally in its init script).
Expendable is a program for modelling things such as the offset facility of a mortgage account; a Fixed Term Deposit, to be paid into the mortgage account on maturity; a savings account, for situations where it is more beneficial than using the mortgage offset facility; regular withdrawals from savings; lump sum payments; and promotional rate credit cards.
