local time of the process running the command instead of the
process that did the build.

image. Broken in primordial Netpbm, ca 1990.

can be represented as a C unsigned integer. Broken in Netpbm
10.11 (October 2002).

Build: don't create pointer man pages anymore. These were
classic man pages, created by 'make package', one for each
program, that just told the user to get the manual from the web
and that other options for manuals are available at install
time. Getting documentation online is commonplace enough now
that the user doesn't need to be told to do it or that there are
other options. The existence of pointer man pages was,
meanwhile, misleading, since it looked from the outside like
they actually contained documentation.
Build: Don't package or install Manweb setup (for accessing
manuals on the web with Manweb). Probably 100% unused and
distracting.
Debian package: change dependencies to be compatible with
Debian 8.

Add -version.

libnetpbm: Add pm_system2(), pm_system2_lp(), pm_system2_vp() -
same as pm_system(), etc. but returns the termination status.

-add, -multiply, -mean, -min, -max. Broken in Netpbm 10.41
(December 2007).

explicitly set to the width you get when you don't specify
width.
pbmtext: ignore -nomargins when -width is specified.
pbmtext: report when line ends are dropped because of
truncation.
pbmtext: Fix bug: if input has a code point that is not in the
font, Pbmtext substitutes space, but behavior is undefined if
font doesn't have space either. Now it aborts the program in
that case.

"pkgsrc" changes:
- Add a lot of patches written by Thomas Klausner and me to make this
compile with PNG 1.5.
* Pnmtopng: -libversion doesn't report level of linked libz.
It was a modularity violation and caused build failures on
Mac OS X, because Pnmtopng per se doesn't know about libz --
it's used by libpng.

I lowered the requirement to _XOPEN_SOURCE=500 and the build succeeded.
While here I'll note that PR pkg/42897 (netbpm link error on Solaris 10)
should now be fixed by libpng-1.2.41nb1.
changes: many bugfixes, especially:
xpmtoppm: fix wild pointer with color index > 127.
which fixes a stack-based buffer overflow (CVE-2009-4274)

helps to detect problems
Changes 10.34:
* Add pamthreshold, pamx, pamtoxvmini.
* pammasksharpen: Add -threshold.
* pnmtopng: make "N colors found" message verbose-only.

bogus "rowBytes" value.
* Redo asprintfN(), etc. so as not to use va_list in a way
that doesn't work on some machines.
* cameratopam: remove definition of memmem() so it doesn't collide
with same in some C libraries. Add memmemN() and MEMEQ to libnetpbm.

Add pamtosvg.
g3topbm: Add -width, -paper_size.
libnetpbm / most newer programs: Fix bug that produces
plain format output when it should be raw because

programs just copy the input pam to the output pam.
pamflip: fix bug with left/right flip of PBM that has
width an even multiple of 8 plus something less than 8.
pnmquant: turn on autoflush when creating seekable file.
