+.SH NAME
+vips \- run vips operations from the command line
+.SH SYNOPSIS
+.B vips [options] [command] [command-options] [command-args]
+.SH DESCRIPTION
+.B vips(1)
+is the VIPS universal main program. You can use it to run any VIPS operation
+from the command line, to query the VIPS class hierarchy, and to
+maintain parts of the VIPS library.
+
+To run a VIPS operation, the first argument should be the name of the
+operation
+and following arguments should be the operation arguments. For example:
+
+  $ vips invert lena.v lena2.v
+
+.SH OPTIONS
+.TP
+.B -l BASE-NAME, --list=BASE-NAME       
+List operations below BASE-NAME. This prints a one-line summary of every
+operation in vips below the class BASE-NAME, where BASE-NAME may be a full
+vips class name, or a nickname. 
+
+If BASE-NAME is not supplied, this will list all classes below VipsOperation.
+
+.TP
+.B -p PLUGIN, --plugin=PLUGIN       
+Load PLUGIN. Note that plugins in $VIPSHOME/lib/vips-plugins-MAJOR.MINOR are 
+loaded automatically.
+
+.TP
+.B -v, --version
+Show VIPS version.
+
+.TP
+.B -c NAME, --completion NAME
+Print completions for 
+.B NAME
+
+.SH COMMANDS
+
+.TP
+.B operation-name operation-arguments
+Execute a named operation, for example add. 
+
+.SH EXAMPLES

+.TH VIPSEDIT 1 "30 June 1993"
+.SH NAME
+vipsedit \- edit header of a vips image file
+.SH SYNOPSIS
+.B vipsedit [OPTION...] vipsfile
+.SH DESCRIPTION
+.B vipsedit 
+alters a VIPS image file's header. This is useful for setting the resolution, 
+for example.
+
+The options are:
+
+  -x, --xsize=N       set Xsize to N
+  -y, --ysize=N       set Ysize to N
+  -b, --bands=N       set Bands to N
+  -f, --format=F      set BandFmt to F (eg. uchar)
+  -i, --interpretation=I        
+                      set Interpretation to I (eg. xyz)
+  -c, --coding=C      set Coding to C (eg. labq)
+  -X, --xres=R        set Xres to R pixels/mm
+  -Y, --yres=R        set Yres to R pixels/mm
+  -u, --xoffset=N     set Xoffset to N
+  -v, --yoffset=N     set Yoffset to N
+  -e, --setext        replace extension block with stdin
+
+Be very careful when changing Xsize, Ysize, BandFmt or Bands. vipsedit does no
+checking!
+
+.SH EXAMPLES
+To set the Xsize to 512 and Bands to 6:
+
+  vipsedit --xsize=512 --bands=6 fred.v
+
+or
+
+  vipsedit -x 512 -b 6 fred.v
+
+Extract the XML metadata from an image with
+.B vipsheader(1),
+edit it, and reattach with 
+.B vipsedit(1).
+
+  vipsheader -f getext fred.v | sed s/banana/pineapple/ | vipsedit -e fred.v
+
+.SH RETURN VALUE
+returns 0 on success and non-zero on error.

+.SH NAME

+.SH SYNOPSIS
+vipsheader [OPTIONS ...] files ...
+.SH DESCRIPTION
+.B vipsheader(1)
+prints image header fields to stdout.
+
+.SH OPTIONS
+
+.TP
+.B -a, --all
+Show all fields. Fields are displayed to be convenient for humans to
+read, so binary data, for example, is summarized rather than simply printed.
+
+.TP
+.B -f FIELD, --field=FIELD
+Print the value of
+.B FIELD
+from the image header. Fields are printed in a way suitable for programs to
+understand, so, for example, binary data is base64-encoded and printed as a
+stream of characters.
+
+The special field name
+.B getext
+prints the VIPS extension block: the XML defining the image metadata. You can
+alter this, then reattach with
+.B vipsedit(1).
+
+You can use multiple "-f" arguments to print the values
+of many fields.

+.SH NAME
+vipsprofile \- analyze vips profiles
+.SH SYNOPSIS
+.B vipsprofile
+.SH DESCRIPTION
+.B vipsprofile(1)
+analyzes the file written by the --vips-profile option, calculates some
+statistics, and draws a graph of evaluation.
+
+Run any vips program with the --vips-profile option to generate a file called
+"vips-profile.txt". This contains timing information about CPU use, memory use
+and thread synchronisation. 
+
+Run
+.B vipsprofile(1)
+to load this file, calculate some 
+statistics, and draw a graph of evaluation saved to vips-profile.svg. This
+analysis can help track down performance problems. 
+
+For example:
+
+  $ vips sharpen shark.jpg x.jpg --vips-profile
+  recording profile in vips-profile.txt

+  reading from vips-profile.txt

+.TH VIPSTHUMBNAIL 1 "13 May 2010"
+.SH NAME
+vipsthumbnail \- make thumbnails of image files
+.SH SYNOPSIS
+.B vipsthumbnail [flags] imagefile1 imagefile2 ...
+.SH DESCRIPTION
+.B vipsthumbnail(1)
+processes each 
+.B imagefile
+in turn, shrinking each image to fit within a 128 by 128 pixel square.
+The shrunk image is written to a new file named
+.B tn_imagefile.jpg.
+This program is typically faster and uses less memory than
+other image thumbnail programs.
+
+For example:
+
+ $ vipsthumbnail fred.png jim.tif
+
+will read image files 
+.B fred.png
+and 
+.B jim.tif
+and write thumbnails to the files
+.B tn_fred.jpg
+and
+.B tn_jim.jpg.
+
+ $ vipsthumbnail --size=64 -o thumbnails/%s.png fred.jpg
+
+will read image file
+.B fred.jpg
+and write a 64 x 64 pixel thumbnail to the file 
+.B thumbnails/fred.png.
+
+.SH OPTIONS
+.TP
+.B -s N, --size=N
+Set the output thumbnail size to 
+.B N 
+x 
+.B N 
+pixels. 
+
+You can use "MxN" to specify a rectangular bounding box.
+The image is shrunk so that it just fits within this area, images
+which are smaller than this are expanded. 
+
+Use "xN" or "Mx" to just resize on
+one axis. 
+
+Append "<" to only resize if the input image is smaller than the
+target, append ">" to only resize if the input image is larger than the target.
+
+.TP
+.B -o FORMAT, --output=FORMAT     
+Set the output format string. The input filename has any file type suffix
+removed, then that value is substituted into 
+.B FORMAT
+replacing
+.B %s. 
+If 
+.B FORMAT
+is a relative path, the name of the input directory is prepended. In other
+words, any path in
+.B FORMAT
+is relative to the directory of the current input file.
+
+The default value is
+.B tn_%s.jpg
+meaning JPEG output, with
+.B tn_
+prepended. You can add format options too, for example
+.B tn_%s.jpg[Q=20]
+will write JPEG images with Q set to 20.
+
+.TP
+.B -e PROFILE, --eprofile=PROFILE        
+Export thumbnails with this ICC profile. Images are only colour-transformed if
+there is both an output and an input profile available. The input profile can
+either be embedded in the input image or supplied with the
+.B --iprofile
+option.
+
+.TP
+.B -i PROFILE, --iprofile=PROFILE        
+Import images with this ICC profile, if no profile is embedded in the image. 
+Images are only colour-transformed if
+there is both an output and an input profile available. The output profile
+should be supplied with the
+.B --oprofile
+option.
+
+.TP
+.B -c, --crop
+Crop the output image down. The image is shrunk so as to completely fill the
+bounding box in both axes, then any excess is cropped off. 
+
+.TP
+.B -d, --delete
+Delete the output profile from the image. This can save a small amount of
+space. 
+
+.TP
+.B -t, --rotate
+Auto-rotate images using EXIF orientation tags. 
+
+.TP
+.B -a, --linear
+Shrink images in linear light colour space. This can be much slower. 
+
+.SH RETURN VALUE
+returns 0 on success and non-zero on error. Error can mean one or more
+conversions failed.
