Make only recompiles the m4 file if it is newer than the compiled target.

I used RCS, which had a version number per file. Later when I moved to Arch, I changed to timestamps generated in m4 (ie: syscmd(`date +%s') ) because Arch doesn't update version header data. > > Right now the only solution I see is to: > 1. checkout the config tree. > 2. copy the config tree to a staging area. > 3. use editfiles to modify the files in the stage. > 4. copy the staging tree into the system and activate a restart as necessary. > > But that's an awful lot of work... > > Maybe subversion has some tools I can use to manage versions of > individual files; but even then a single file on the system may be > changed by two or more config files.
