emerge-execute-line
emerge-execute-line is an interactive compiled Lisp function in `emerge.el
'.
(emerge-execute-line)
Run Emerge using files named in current text line.
Looks in that line for whitespace-separated entries of these forms:
a=file1
b=file2
ancestor=file3
output=file4
to specify the files to use in Emerge.
In addition, if only one of `a=file' or `b=file' is present, and `output=file'
is present:
If `emerge-execute-line-deletions' is non-nil and `ancestor=file' is present,
it is assumed that the file in question has been deleted, and it is
not copied to the output file.
Otherwise, the A or B file present is copied to the output file.
