I see.  This is interesting.  I guess I don't care too much about disk
size and I like the idea that the thing doesn't have to depend on other
parts of the system.  But if I can save space for free, I'll do it.  This
brings me to "strip":  Does anyone understand the "strip" command.  I
don't, but I have used it on compiled binaries.  It really reduces the
size and they seem to work just the same.  Weird, no?

Here's an example using dillo:

# cp dillo dillo2
# strip dillo2
# ls -lAF dillo*
-rwxr-xr-x   1 root     other     6413104 Mar 13 16:58 dillo*
-rwxr-x---   1 root     other      364924 Mar 14 01:05 dillo2*
# mv dillo2 dillo

Hmmm... the strip command finished in less than one second and the dillo
file was reduced by more than 6 MB down to a mere 365 KB.  Interesting!

Regarding dependencies:  I have all these even with the small file:

ldd /usr/local/bin/dillo
        librt.so.1 =>    /usr/lib/librt.so.1
        libpng.so.2 =>   /usr/local/lib/libpng.so.2
        libz.so =>       /usr/local/lib/libz.so
        libpthread.so.1 =>       /usr/lib/libpthread.so.1
        libgtk-1.2.so.0 =>       /usr/local/lib/libgtk-1.2.so.0
        libgdk-1.2.so.0 =>       /usr/local/lib/libgdk-1.2.so.0
        libgmodule-1.2.so.0 =>   /usr/local/lib/libgmodule-1.2.so.0
        libglib-1.2.so.0 =>      /usr/local/lib/libglib-1.2.so.0
        libdl.so.1 =>    /usr/lib/libdl.so.1
        libXext.so.0 =>  /usr/openwin/lib/libXext.so.0
        libX11.so.4 =>   /usr/openwin/lib/libX11.so.4
        libsocket.so.1 =>        /usr/lib/libsocket.so.1
        libnsl.so.1 =>   /usr/lib/libnsl.so.1
        libm.so.1 =>     /usr/lib/libm.so.1
        libc.so.1 =>     /usr/lib/libc.so.1
        libaio.so.1 =>   /usr/lib/libaio.so.1
        libdga.so.1 =>   /usr/openwin/lib/libdga.so.1
        libmp.so.2 =>    /usr/lib/libmp.so.2
        libthread.so.1 =>        /usr/lib/libthread.so.1
        /usr/platform/SUNW,Ultra-2/lib/libc_psr.so.1

So maybe the big difference in size is all about the stripping (whatever
that is!).

Best,

Mike
