Any system without the DISPLAY (or DECW$DISPLAY) +# environment variable will be assumed to be Non-X. + +# You can append a ';' followed by "q=#.#", e.g., ; q=0.002 +# to set the quality parameter for the Content-Type, which can be +# included in the Accept: header Lynx sends to http servers (the +# default quality value is 1.0, and Lynx appends the parameter +# to the Content-Type only if the value is less than 1.0). + +# You can append a ';' followed by "mxb=#", e.g., ; mxb=1000000 +# to set the maxbytes parameter for the Content-Type, which can be +# included in the Accept: header Lynx sends to http servers (the +# default maxbytes value is 0, meaning no maximum, and Lynx appends +# the parameter to the Content-Type only if the value exceeds 0). + +# The following line is for sites where xv understands jpeg but xloadimage +# is preferred. +# +# the test line specifies that this viewer should only be used if +# the display variable is set. +image/jpeg; xv %s; test=test -n "$DISPLAY" + +# The following sends all other image subtypes to xloadimage +#image/*; xloadimage %s; ; test=test -n "$DISPLAY" + +# The following sends all other image subtypes to xv +image/*; xv %s; ; test=test -n "$DISPLAY" + + +# If you have an interactive Postscript interpreter, you should think carefully +# before replacing lpr with it in the following line, because PostScript +# can be an enormous security hole.

This problem is compounded by the fact +# that some programs, notably Mosaic, do not implement the "test" clause in +# mailcap files. If you are using Lynx and X Mosaic together you should +# place all X-centric entries before non-X entries. X Mosaic will use +# whichever entry is defined first so further entries will be ignored. +# +# Lynx exports the environment variable LYNX_VERSION, so it can be tested +# by scripts to determine if Lynx is running or not. However, the string +# test=test -n "$LYNX_VERSION" +# is handled simply as a flag which yields success when Lynx encounters it +# in the mailcap file (i.e., Lynx does not bother to execute "test" via a +# system() call to find out if it's running, because it obviously is). +# Inclusion of the string for that test can be used to prevent other +# software which reads the mailcap file from acting on assignments intended +# only for Lynx. The string +# test=test -z "$LYNX_VERSION" +# similarly is treated by Lynx simply as a flag which yields failure. + |
