The "/whatis" page:
Additional query parameters:
ln - show line numbers
ln=N - highlight line number N
ln=M-N - highlight lines M through N inclusive
ln=M-N+Y-Z - highlight lines M through N and Y through Z (inclusive)
verbose - show more detail in the description
download - redirect to the download (artifact page only)
name=NAME - filename or hash as a query parameter
filename=NAME - alternative spelling for "name="
fn=NAME - alternative spelling for "name="
ci=VERSION - The specific check-in to use with "name=" to
identify the file.
The /artifact page show the complete content of a file
identified by HASH. The /whatis page shows only a description
of how the artifact is used. The /file page shows the most recent
version of the file or directory called NAME, or a list of the
top-level directory if NAME is omitted.
For /artifact and /whatis, the name= query parameter can refer to
either the name of a file, or an artifact hash. If the ci= query
parameter is also present, then name= must refer to a file name.
If ci= is omitted, then the hash interpretation is preferred but
if name= cannot be understood as a hash, a default "tip" value is
used for ci=.
For /file, name= can only be interpreted as a filename. As before,
a default value of "tip" is used for ci= if ci= is omitted.
