I use a combination of "standard" library routines kept as include files in
source code format, and copying from previous projects as appropriate.  It
also helps a lot that all projects use mostly the same overall structure and
build environment.

For example, one of the standard library routines initializes the I/O ports
according to the preprocessor /INBIT and /OUTBIT commands in the include
file.  This has lots of assembly time conditionals and therefore looks like
a mess.  In fact, some of it was machine generated.  However, I haven't been
in there in a long time.  It's something I just use and don't have to think
about.  Each project has it's own PORT module, but that's just a reference
to the project include file, a reference to the PORT library file, and a END
directive.  My MAKE_PIC_MODULE script automatically generates this if you
ask it to make a module where a template of the same name already exists,
otherwise it uses the generic module template.

Using lots of macros helps too.  Since a macro causes no code to be emitted
unles it is envoked, I put all my "standard" macros in a single file that
gets included in all files.  That file is STD.INS.ASPIC, and has grown to
over 5000 lines.

Some things don't lend themselves well to standardization.  You'd think
there would be a common way to use the A/D, for example, but yet every
project has a little different wrinkle.  There I might initialize the code
by copying the module from another project, then change it from there.
That's what my CLONE_PIC_MODULE script is for.  It copies a module from
another project, and renames things, like the include file reference, to the
new project.
